Abstract:
Electrically conductive polymer composites are in high demand for modern technologies, however, the intrinsic brittleness of conducting conjugated polymers and the moderate electrical conductivity of engineering polymer/carbon composites have highly constrained their applications. In this work, super high electrical conductive polymer composites were produced by a novel hot embossing design. The polydimethylsiloxane (PDMS) composites containing short carbon fiber (SCF) exhibited an electrical percolation threshold at 0.45 wt % and reached a saturated electrical conductivity of 49 S/m at 8 wt % of SCF. When reducing the sample thickness from 1.0 to 0.1 mm by the hot embossing process, a compression-induced percolation threshold occurred at 0.3 wt %, while the electrical conductivity was further enhanced to 378 S/m at 8 wt % SCF. Furthermore, the addition of a second nanofiller of 1 wt %, such as carbon nanotube or conducting carbon black, further increased the electrical conductivity of the PDMS/SCF (8 wt %) composites to 909 S/m and 657 S/m, respectively. The synergy of the densified conducting filler network by the mechanical compression and the hierarchical micro-/nano-scale filler approach has realized super high electrically conductive, yet mechanically flexible, polymer composites for modern flexible electronics applications.

Abstract:
Polymeric materials are typically considered as insulators, and in fact important applications do rely on their poor conductivity— e.g., electrical cable insulation and charged dielectric films (electrets, electrical analogs of magnets), the latter finding use in microphones. Research in the last decade, however, has lead to the discovery of polymeric materials with extremely high conductivity, approaching that of copper. This brief article will highlight recent work in the synthesis, processing and applications of these novel materials.Typical polymers, the oxidant (or “dopant”) used to create carriers, and room temperature conductivities are given in Table I. A key feature shared by these materials is delocalized (at least over a few repeat units) π-electron density. Such unsaturated polymers facilitate carrier generation because of the ability for resonance derealization of the resulting radical ions, which can also offer good intramolecular carrier mobility. In addition, the geometry of π-orbitals allows for good orbital overlap and encourages inter molecular carrier transport.That the polymer chains are considerably shorter than typical sample dimensions indicates that intermolecular transport is dominant, especially in view of the disorder observed in most conducting polymer systems. However, as the number of defects (crosslinks, “twists” which inhibit conjugation) decreases, it might be anticipated that carriers can travel greater distances along a chain before a (presumably) higher activation energy, inter molecular electron transfer becomes necessary, thus affording higher conductivity. Indeed, it has been recently reported that samples of very high quality, oriented polyacetylene, when treated with iodine, exhibit conductivities approaching that of copper at room temperature.

Abstract:
For the past 50 years, conventional insulating-polymer systems have increasingly been used as substitutes for structural materials such as wood, ceramics, and metals because of their high strength, light weight, ease of chemical modification/customization, and processability at low temperatures. In 1977 the first intrinsic electrically conducting organic polymer—doped polyacetylene—was reported, spurring interest in “conducting polymers.” Intrinsically conducting polymers are completely different from conducting polymers that are merely a physical mixture of a nonconductive polymer with a conducting material such as metal or carbon powder. Although initially these intrinsically conducting polymers were neither processable nor air-stable, new generations of these materials now are processable into powders, films, and fibers from a wide variety of solvents, and also are airstable. Some forms of these intrinsically conducting polymers can be blended into traditional polymers to form electrically conductive blends. The electrical conductivities of the intrinsically conductingpolymer systems now range from those typical of insulators (<10−10 S/cm (10−10 Ω−1 cm1)) to those typical of semiconductors such as silicon (~10 5 S/cm) to those greater than 10+4 S/cm (nearly that of a good metal such as copper, 5 × 105 S/cm). Applications of these polymers, especially polyanilines, have begun to emerge. These include coatings and blends for electrostatic dissipation and electromagnetic-interference (EMI) shielding, electromagnetic-radiation absorbers for welding (joining) of plastics, conductive layers for light-emitting polymer devices, and anticorrosion coatings for iron and steel.The common electronic feature of pris tine (undoped) conducting polymers is the π-conjugated system, which is formed by the overlap of carbon pz orbitals and alternating carbon-carbon bond lengths.

Abstract:
Intrinsically conducting polymers (ICPs) have been intensively the subject of research since these polymers have superlative electrical and thermophysical properties. Due to the low hydrogen content and aromatic structure, they show perfect chemical, thermal, and oxidative stability and are practically insoluble in all common solvents. Also these polymers are latently electrical conducting materials, especially when doped. Polypyrole (PPy) is a very promising conducting polymer. It can be in easy way processes and has many interesting electrical properties. Also ıt is chemically and thermally stable. Like many other fully aromatic polymers, PPy is an electrical insulator, however, when oxidized it becomes an electrical conductor.The conductivity of PPy strongly consists in the preparation technique, and on the polymer additives and can be increased by about two orders of magnitude. In this study, electrically conductive hollow fabrics were prepared via ın situ chemical polymerization method and scanning electron microscopy (SEM) and electrical properties of conductive hollow fabrics were invesigated.

Abstract:
Polymer composite has attracted many researchers from various field of application due to its unique features and properties including light weight, low cost, ease to process and shaping and corrosion resistant [1-3]. Fillers is typically added to enhance the chemical and physical properties of polymers [4, 5]. One of the properties is the electrical conductivity. Carbon based filler such as graphite (G), carbon black (CB), carbon fibers (CF) and carbon nanotubes (CNT) has been extensively used to improve electrical properties of polymer composite [6-8]. Electrical properties of the composite can be explained from percolation theory which means electrical percolation in mixtures of electrically conducting and non-conducting materials [9]. The concentration of conducting phase must above the critical value called percolation threshold, in order for the material become electrically conductive [10].

Abstract:
Conductive polymers are promising for application in the medical and sport sectors, e.g. for thin wearable health monitoring systems. While many today’s electrodes contain either carbon or metals as electrically conductive filler materials, product design manufacturing has an increasing interest in the development of metal free and carbon free, purely polymer based electrode materials. While conducting polymers have generally rather low electrical conductivities compared to metals or carbon, they offer broad options for industrial processing, as well as for dedicated adjustments of final product properties and design aspect, such as colour, water repellence, or mechanical flexibility in addition to their electrical properties. The development of electrically conducting polymer blends, based on conductive polymers is thus timely and of high importance for the design of new attractive flexible electrodes. We have developed material formulation and processing techniques for the fabrication of self-supporting thin film electrodes based on polyaniline (PANI) and polyvinylidene fluoride (PVDF) blends. Electrical four-point probing was used to evaluate the electrode conductivity for different processing and fabrication techniques. Optical microscopy and atomic force microscopy measurements corroborate the observed electrical conductivity obtained even at low PANI concentrations revealing the nanoscale material distribution within the blends. Our self-supporting thin film electrodes are flexible, smooth, and water repellent and were furthermore successfully tested under bending and upon storage over a period of several months. This opens new perspectives for the design of metal free and carbon free flexible electrodes for medical, health, and sports applications.

Abstract:
A new system of thermoset styrene-based shape-memory polymer (SMP) filled with carbon black (CB) is investigated. To realize the electroactive stimuli of SMP, the electrical conductivity of SMP filled with various amounts of CB is characterized. The percolation threshold of electrically conductive SMP filled with CB is about 3% (volume fraction of CB), which is much lower than many other electrically conductive polymers. When applying a voltage of 30V, the shape recovery process of SMP/CB(10 vol%) can be realized in about 100s. In addition, the thermomechanical properties are also characterized by differential scanning calorimetery (DSC).

Abstract:
AbstractThis work is a review of the literature on the possibilities for electroplating of polymer materials. Methods of metalizing polymers and their composites were presented and discussed. Information from various publications on the electrical properties of polymers and polymer composites was collected and discussed. The most important results on the electroplating of conductive polymers and conductive composites were presented and compared. This work especially focuses on the electrical conductivity of polymer materials. The main focus was the efficiency of metal electrodeposition. Based on the analyzed publications, it was found that electrically deposited metal layers on conductive polymeric materials show discontinuity, considerable roughness, and different layer thickness depending on the distance from the contact electrode. The use of metal nanoparticles (AgNWs) or nickel nanoparticles (NiNPs) as a filler enables effective metallization of the polymer composite. Due to the high aspect ratio, it is possible to lower the percolation threshold with a low filler content in the polymer matrix. The presented review reveals many of the problems associated with the effectiveness of the electroplating methods. It indicates the need and direction for further research and development in the field of electroplating of polymer materials and modification of their electrical properties.

Abstract:
The growing demand in portable and compact consumer devices and appliances has resulted in the need for the miniaturisation of electronic components. These miniaturised electronic components are sensitive and susceptible to damage by voltages as low as 20V. Electrically conductive styrenic thermoplastics are widely used in electronic packaging applications to protect these sensitive electronic components against electro-static discharge (ESD) during manufacturing, assembly, storage and shipping. Such ESD applications often require the optimal volume resistance range of ≥ 1.0x105 to < 1.0x108 Ω. The best known method to render styrenic thermoplastics conductive is by the incorporation of conductive fillers, such as carbon black but the main limitation is the difficulty in controlling the conductivity level due to the steep percolation curve. Thus the aim of this research is to develop electrically conductive styrenic thermoplastics by blending several styrenic resins with polymeric conductive additives to achieve optimal volume resistance range for ESD applications with the ease in controlling the conductivity level.

Abstract:
Electrically conductive polymer composites, i.e. polymers filled with conductive fillers, may display a broad range of electrical properties. A rational design of fillers, filler surface chemistry and filler loading can tune the electrical properties of the composites to meet the requirements of specific applications. In this dissertation, two studies were discussed. In the first study, highly conductive composites with electrical conductivity close to that of pure metals were developed as environmentally-friendly alternatives to tin/lead solder in electronic packaging. Conventional conductive composites with silver fillers have an electrical conductivity 1~2 orders of magnitude lower than that of pure, even at filler loadings as high as 80-90 wt.%. It is found that the low conductivity of the polymer composites mainly results from the thin layer of insulating lubricant on commercial silver flakes. In this work, by modifying the functional groups in polymer backbones, the lubricant layer on silver could be chemically reduced in-situ to generate silver nanoparticles. Furthermore, these nanoparticles could sinter to form metallurgical bonds during the curing of the polymer matrix. This resulted in a significant electrical conductivity enhancement up to 10 times, without sacrificing the processability of the composite or adding extraneous steps. This method was also applied to develop highly flexible/stretchable conductors as building block for flexible/stretchable electronics. In the second study, a moderately conductive carbon/polymer composite was developed for use in sensors to monitor the thermal aging of insulation components in nuclear power plants. During thermal aging, the polymer matrix of this composite shrank while the carbon fillers remained intact, leading to a slight increase in filler loading and a substantial decrease in the resistivity of the sensors. The resistivity change was used to correlate with the aging time and to predict the need for maintenance of the insulation component according to Arrhenius’ equation. This aging sensor realized real-time, non-destructive monitoring capability for the aging of the target insulation component for the first time.

Abstract:
Layer-by-layer (LbL) assembly was used to produce highly conductive thin films with carbon black (CB) and polyelectrolytes. The effects of sonication and pHadjustment of the deposition mixtures on the conductivity and transparency of deposited films were studied. Drying temperature was also evaluated with regard to thin film resistance. Sonication and oven drying at 70oC produced films with the lowest sheet resistance (~ 1500 Ω/sq), which corresponds to a bulk resistivity of 0.2 Ω⋠cm for a 14- bilayer film that is 1.3 μm thick. Increasing the pH of the PAA-stabilized mixture and decreasing the pH of the PEI-stabilized mixture resulted in films with 70% transparency due to thinner deposition from increased polymer charge density. Varying the number of bilayers allows both sheet resistance and optical transparency to be tailored over a broad range. Variation of deposition mixture composition led to further reduction of sheet resistance per bilayer. A 14 bilayer film, made from mixtures of 0.25wt% carbon black in 0.05wt% PAA and plain 0.1wt% PEI, was found to have a sheet resistance of approximately 325 Ω/sq. Bulk resistivity was not improved due to the film being 8 μm thick, but this combination of small thickness and low resistance is an order of magnitude better than carbon black filled composites made via traditional melt or solution processing. Applications for this technology lie in the areas of flexible electronics, electrostatic charge dissipation, and electromagnetic interference shielding.

Abstract:
Polymers and polymer-based composite materials with electro-conductive properties, respectively, are materials with several potential applications. New materials are being offered in every area and novel products are constantly being introduced. Among these new materials, composites made of electro-conductive monofilaments and insulating polymers are nowadays being used as antistatic materials in the carpets and textiles industries. One promising approach for the manufacture of this kind of material is to generate the electrically conductive fibres in-situ, that is, during the actual forming process of the component. The main objective of this project was to establish the feasibility of producing electrically conductive polyaniline (PANI) fibres within a suitable polymer matrix by means of the development of a suitable processing strategy, which allows the fabrication of an anisotropically conducting composite. It is remarkable, however, that layered structures of the conducting filler were also formed within the matrix material. The latter morphology, particularly observed in compression moulded specimens of a specific polymer system, was also in good agreement with that inferred by means of a mathematical model. Experimentation was carried out with three different PANI conductive complexes (PANIPOLTM). They were initially characterised, which assisted in the identification of the most suitable material to be deformed into fibres. Preliminary processing was carried out with the selected PANIPOLTM complex, which was blended with polystyrene-polybutadiene-polystyrene (SBS), low density polyethylene (LDPE) and polypropylene (PP), respectively. The resultant blends were formed by ram extrusion, using a capillary die, to induce the deformation of the conducting phase into fibres. The morphological analysis performed on the extrudates suggested that the most suitable polymer matrix was SBS. Further experimentation was carried out with the polymer system selected. The relationships between the content of conductive complex in the composites and their electrical conductivity and microstructure were established. The blends were compression moulded and they displayed a morphology of layered domains of the conducting phase within the SBS matrix. The behaviour of the conductivity with respect to the PANIPOLTM complex in the compression moulded blends was found to be characteristic of a percolating system with a threshold as low as 5 weight percent of the conducting filler in the blends. The morphological analysis performed on the extruded blends suggested that the conducting phase was deformed into elongated domains, aligned parallel to the extrusion direction, which in some cases displayed a considerable degree of continuity and uniformity. The level of electrical conductivity in the extrudates was considerably lower than that of their corresponding non-extruded blends. This was attributed to a lack of continuity in the conducting elongated domains produced in-situ within the SBS matrix. Percolation theory and a generalisation of effective media theories were used to model the behaviour of the conductivity with respect to the content of PANIPOLTM in the compression moulded blends. Both approaches yielded similar values for the critical parameters, which were also in good agreement with the percolation threshold experimentally observed. The results of the modelling suggested that, at the percolation threshold, the morphology of the composite may consists of aggregates of flattened polyaniline particles forming very long layered structures within the SBS matrix, which is in agreement with the results of the morphological analysis.

Abstract:
With excellent electrical, thermal and mechanical properties as well as large specific surface area, graphene has been applied in next-generation nano-electronics, gas sensors, transparent electrical conductors, thermally conductive materials, and superior energy capacitors etc. Convenient and productive preparation of graphene is thereby especially important and strongly desired for its manifold applications. Chemically developed functionalized graphene from graphene oxide (GO) has significantly high productivity and low cost, however, toxic chemical reduction agents (e.g. hydrazine hydrate) and raised temperature (400-1100°C) are usually necessary in GO reduction yet not preferred in current technologies. Here, microwaves (MW) are applied to reduce the amount of graphene oxide (GO) at a relatively low temperature (~165°C). Experimental results indicate that resurgence of interconnected graphene-like domains contributes to a low sheet resistance with a high optical transparency after MW reduction, indicating the very high efficiency of MW in GO's reduction. Moreover, graphene is usually recumbent on solid substrates, while vertically aligned graphene architecture on solid substrate is rarely available and less studied. For TIMs, electrodes of ultracapacitors, etc, efficient heat dissipation and electrical conductance in normal direction of solid surfaces is strongly desired. In addition, large-volume heat dissipation requires a joint contribution of a large number of graphene sheets. Graphene sheets must be aligned in a large scale array in order to meet the requirements for TIM application. Here, thermally conductive fuctionalized multilayer graphene sheets (fMGs) are efficiently aligned in a large scale by vacuum filtration method at room temperature, as evidenced by SEM images and polarized Raman spectroscopy. A remarkably strong anisotropy in properties of aligned fMGs is observed. Moreover, VA-fMG TIMs are prepared by constructing a three-dimensional vertically aligned functionalized multilayer graphene architecture between contact Silicon/Silicon surfaces with pure Indium as a metallic medium. Compared with their counterpart from recumbent A-fMGs, VA-fMG TIMs have significantly higher equivalent thermal conductivity and lower contact thermal resistance. Electrical and thermal conductivities of polymer composite are also greatly interested here. Previous researches indicated that filler loading, morphology of fillers, and chemical bonding across filler/polymer interfaces have significant influence on electrical/thermal conductivity of polymer composite. Therefore, the research also pays substantial attention to these issues. First, electrical resistivity of CPCs is highly sensitive on volume or weight ratio (filler loading) of conductive fillers in polymer matrix, especially when filler loading is close to percolation threshold (pc). Thermal oxidation aging usually can cause a significant weight loss of polymer matrix in a CPC system, resulting in a filler loading change which can be exhibited by a prompt alteration in electrical resistivity of CPCs. Here, the phenomena are applied as approach for in-situ monitoring thermal oxidation status of polymeric materials is developed based on an electrical sensors based on conductive polymeric composites (CPCs). The study developed a model for electrical resistivity of sensors from the CPCs as a function of aging time at constant aging temperature, which is in a good agreement with a Boltzmann-Sigmoidal equation. Based on the finding, the sensors show their capability of in-situ in-situ monitor and estimate aging status of polymeric components by a fast and convenient electrical resistance measurement. Second, interfacial issues related to these thermal conductive fillers are systemically studied. On the one hand, the study focuses on relationship between morphology of h-BN particles and thermal conductivity of their epoxy composites. It is found that spherical-agglomeration of h-BN particles can significantly enhance thermal conductivity of epoxy resin, compared with dispersed h-BN plates, by substantially reducing specific interfacial area between h-BN and epoxy resin. On the other hand, surface of high thermal conductive fillers such as SiC particles and MWNTs are successfully functionalized, which makes their surface reactive with bisphenol A diglycidyl ether and able to form chemical bonding between fillers and epoxy resin. By this means, thermal conductivity of polymer composites is found to be significantly enhanced compared with control samples, indicating the interfacial chemical bonding across interface between thermal conductive fillers and polymer matrix can promote heat dissipation in polymeric composites. The finding can benefit a development of high thermal conductive polymer composites by interfacial chemical bonding enhancement to meet the demanding requirements in current fine pitch and Cu/low k technology.

Abstract:
Carbon nanotube (CNT)-polymer composites were prepared by segregated network approach. CNTs were served as conductive fillers in a polymer matrix to synthesize electrically conducting polymer composites. In the segregated network composites, the thermoelectric properties were further improved by replacing Gum Arabic (GA) with electrically conductive stabilizer PEDOT:PSS doped with dimethyl sulfoxide (DMSO). The electrical and thermal conductivities and Seebeck coefficient were measured to determine the thermoelectric property of the polymer composites. The electrical conductivity of the composites with 9.8wt% of CNT was 3191.8 S/m whereas that of 10wt% CNT composite with GA sample was 400 S/m.

Abstract:
Abstract Previous studies have shown that metallic coatings can be successfully cold sprayed onto several polymer substrates. The electrical performance of the cold-sprayed polymers, however, is not generally sufficient enough to utilize them as an electronic device. In this paper, an environment-friendly metallization technique has been proposed to fabricate conductive metal patterns onto polymer substrates combining cold spray deposition and electroless plating to address that challenge. Copper feedstock powder was cold sprayed onto the surface of the acrylonitrile-butadiene-styrene (ABS) parts. The as-cold sprayed powders then served as the activating agent for selective electroless copper plating (ECP) to modify the surface of the polymers to be electrically conductive. A series of characterizations are conducted to investigate the morphology, analyze the surface chemistry, and evaluate the electrical performance and adhesion performance of the fabricated coatings. After 6 hours of ECP, the sheet resistance and resistivity of copper patterns on the ABS parts were measured as 2.854 mΩ/sq and 6.699 × 10−7 Ωm respectively. Moreover, simple electrical circuits were demonstrated for the metallized ABS parts through the described method. The results show that low-pressure cold spray (LPCS) and ECP processes could be combined to fabricate electrically conductive patterns on ABS polymer surfaces in an environmental-friendly way.

Abstract:
The application of polymer-based micro-patterns in the field of flexible micro-electronics has become the focus as to replace rigid and planar silicon based integrated circuits with weak bendability. Polyethylene terephthalate (PET) can be used as a substrate because of its excellent flexible and mechanical properties and polyaniline (PANI) is a typical representative of the electrical conductive polymers applicable for this purpose. PANI excels by a stable and controllable electrical conductivity, high environment stability, and ease fabrication. An improvement of electrical conductivity of PANI can be achieved using different nano-particles, such as carbon nanotubes (CNTs). CNTs since their discovery have attracted attention due to their excellent electrical, thermal, and mechanical properties, and had divergent applications, such as complex nano/micro-electronic devices, energy storage and both chemical and bio sensors. This research was focused on the preparation of micro-patterns based on electrically conductive PANI using shaping mold and cold plasma acting as adhesion promoter for PET substrate. The PANI/CNTs nano-composite was used to enhance an electrical conductivity of prepared micropatterns. The adhesion of prepared micro-patterns was evaluated based on the peel tests measurement. Various microscopic techniques, such as profilometry, scanning electron microscopy and atomic force microscopy (AFM), proved the homogeneous structures of prepared polymer based micro-patterns. Broad dielectric spectroscopy and conductive AFM confirmed electrical behavior of prepared micro-patterns.

Abstract:
Abstract Many freight railcars rest on polymer adapter pads made of injection-molded Thermoplastic Polyurethane (TPU) polymers which feature two copper studs to provide electrical conductivity through the pad. This design feature allows signal transmission from the track to the onboard systems, including cargo gates and pneumatic actuators. While in service, the polymer pads experience impact and cyclic loading that produce shear, resulting in the abrasive wear and plastic compression of the copper studs which leads to signal interruptions and loss of function requiring the periodic replacement of these polymer pads. This causes increased downtime due to maintenance and reduced reliability in the automated systems since pad failure is unpredictable. This limitation in current designs is the driving concern behind the effort to create an electrically conductive polymer adapter pad that would provide a durable conductive path between the rail and freight car side-frame. To that end, the University Transportation Center for Railway Safety (UTCRS) has been working on developing a conductive composite blend of TPU and Carbon Nano Fibers (CNF) to create injection-molded polymer composite inserts that can provide the necessary conductivity without the need for the copper studs that are susceptible to wear. Previous work done on this project was successful in creating a TPU-CNF composite insert that provided the required electrical conductivity at full railcar loads but was inconsistent at empty railcar loads. Thus, current work presented here focused on studying the fiber orientation that would produce consistent conductivity at all railcar loads. Based on these findings, a new mold was fabricated to create injection-molded polymer composite inserts with the effective fiber orientation. Laboratory test results show that the newly created composite inserts provide approximately double the needed conductivity required for a 24-Volt railcar valve to actuate when tested under the minimum load conditions an adapter would experience in field service. This paper summarizes the work done on fiber alignment and the results of the testing performed on the UTCRS dynamic bearing test rigs.
