Abstract:

Cellulose/Ag/polyaniline conductive composite with rather excellent electrical conductivity was heterogeneously synthesized in this paper. The UV-Vis analysis indicated that homogeneous nanoAg particles deposited on the surface of cellulose in the form of globe particles. They offered some electrons to polyaniline chains. This behavior resulted to the facts that more polyaniline embedded on cellulose and an integrated electrically conductive network formed. Consequently, the high electrical conductivity of the composite was observed. The value was 3.48 S/cm, which was higher two magnitudes than the electrical conductivity of cellulose/polyaniline composite (2.15×10-2S/cm), and even was higher than the electrical conductivity of pure polyaniline (0.142 S/cm). This paper provided a facile method for the preparation of cellulose/Ag/ polyaniline composite with favorable electrical conductivity.

Abstract:

Electrically conductive porous Si/SiC fiber media were prepared by infiltration of liquid silicon into porous carbon fiber preforms. The series rule of mixture for the effective electrical conductivity was applied to the disc shaped samples to estimate their silicon content, effective electrical conductivity and porosity. The electrical conductivity was estimated by assuming the disc sample as a plate of equivalent geometry, i.e., same thickness, electrode distance and volume. As the volumetric content of silicon in a sample increases from 0.026% to 0.97%, the estimated electrical conductivity increases from 0.17 S/cm to 2.09 S/cm. The porosity of the samples measured by Archimedes principle was in the range of 75~83% and 1~4% less than the one estimated by the series rule of mixture for the effective electrical conductivity.

Abstract:

To clarify the charge compensation mechanism and the way of alloying additives placement, the authors synthesised samples of potassium βʺ-polyferrites with a wide range of mole fraction of introduced doubly charged cations. For these samples, the authors measured the electronic conductivity, cationic conductivity, and performed X-ray diffraction (XRD) analysis. The authors identified the charge compensation mechanism in potassium β″-polyferrite when doped with divalent ions of calcium, strontium, magnesium, and zinc. The charge compensation mechanisms differ depending on the radius of the introduced doubly charged ion. The results of cationic conductivity measurements of potassium β″-polyferrites show the mobility reduction of large calcium and strontium cations of potassium ions. Such additives are quite promising for improving the mechanical strength and thermal stability of the catalyst granules. They also increase the chemical stability of the contact granules. Corrosion resistance of pellets is a critical parameter. It determines the period of effective functioning of the catalyst. The data on electronic conductivity allow one to conclude that the introduction of Mg2+, Zn2+ cations sharply reduces the electron exchange in the structure of potassium β″-polyferrite. This should inevitably cause deactivation of the catalyst, while Ca2+ and Sr2+ ions do not reduce the electron transfer rate. Moreover, using the proposed approach will intensify the research process.

Abstract:

In this work, electrically conductive elastomers were obtained by modifying the organosilicon compound with carbon nanotubes (CNT) “Taunit” and “Taunit-M”. It was found that the use of CNTs with different structures had a different effect on the electrical conductivity of nanomodified composites. The maximum electrical conductivity of 6.94 × 10–9 S/cm of nanomodified composites was achieved at 30 wt. % content of CNT “Taunit”. In the case of using CNT “Taunit-M”, the maximum value of electrical conductivity of 3.06 × 10–2 S/cm was observed for the nanomodified composite containing 6 wt.%. Preliminary drying and mechanical activation of CNTs led to an increase in electrical conductivity by one order of magnitude as a whole.

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:

A suitably modified resin film infusion (RFI) process was used for manufacturing carbon fiber-reinforced composites (CFRCs) impregnated with a resin containing nanocages of glycidyl polyhedral oligomeric silsesquioxane (GPOSS) for enhancing flame resistance and multi-wall carbon nanotubes (MWCNTs) to contrast the electrical insulating properties of the epoxy resin. The effects of the different numbers (7, 14 and 24) of the plies on the equivalent direct current (DC) and alternating current (AC) electrical conductivity were evaluated. All the manufactured panels manifest very high values in electrical conductivity. Besides, for the first time, CFRC strings were analyzed by tunneling atomic force microscopy (TUNA) technique. The electrical current maps highlight electrically conductive three-dimensional networks incorporated in the resin through the plies of the panels. The highest equivalent bulk conductivity is shown by the seven-ply panel characterized by the parallel (σ//0°) in-plane conductivity of 16.19 kS/m. Electrical tests also evidence that the presence of GPOSS preserves the AC electrical stability of the panels.

Abstract:

Introduction. It is confirmed that a dispersion of carbon black when it added to concrete is likely to increase its electrical conductivity. These materials are of great importance for construction for example for civil engineering, transportation and energy industries. In that branches such materials could be used as snow melting systems, protective materials for metal bars, electromagnetically shielded materials. This study is about probable reason of electrically conductive properties in silicate-based material with carbon particles. Materials and methods. Small molecular fragments which are the parts of modified concrete have been considered to investigate contact areas between carbon particles in silicate based material. Fire Fly has been chosen as software. Exchange-correlation phenomenon has been included by using B3LYP. Results. An optimum percentage of modifier in mineral binder leads to the formation of an electrically conductive grid made of carbon nanoparticles. Electrical conductivity of material is influenced by contact areas between these nanoparticles. Quantum chemical molecular models of molecular fragments and interactions between these fragments have been made. Also, the impact of these areas on electrical conductivity was estimated. Conclusions. Quantum chemical molecular models and analysis based on the optimum percentage of the modifier showed that electrical conductivity of the modified concrete depended on an electrons movement along the grid of carbon nanoparticles formed within the mineral matrix. The key role in electrical conductivity of the material plays contact areas between these particles. Electrical conductivity is increasing due to silicate-based components in molecular fragments.

Abstract:

The objective of this study was to impart the electrical conductivity to the polyester fabric by applying polypyrrole having a good atmospheric stability, and to fabricate the superhydrophobic surface by using perfluorodecyltriethoxysilane to increase the durability and practicality of electrically conductive fabric. Nanoscale roughness that is essential for superhydrophobicity was given to polyester fabric by the alkaline hydrolysis. Samples simultaneously subjected to surface hydrophobization and the treatment for electrical conductivity exhibited the excellent electrical conductivity (0.55 kΩ/sq). However, in this case, static contact angle of the water droplet was 148.2°, and shedding angle was >10°, thus confirming that the superhydrophobic property was not exhibited. Samples subjected to surface hydrophobization after the treatment for electrical conductivity had an electrical conductivity and superhydrophobicity with an electrical surface resistivity of 0.87 kΩ/sq, water contact angle of 154.8°, and water shedding angle of 5.0°. This polyester fabric showed reasonable air permeability, water vapor transmission rate, and functional durability to various liquids. The developed fabric can be exposed to a reduced number of washing cycles due to its self-cleaning properties, thereby made able to exhibit a durable conductivity during its use phase.

Abstract:

A new nanocomposite based on conducting polyaniline (PANI) and Algerian montmorillonite clay dubbed Maghnite is proposed to combine conducting and thermal properties (Mag). The PANI-Mag nanocompo-sites samples were made by in situ polymerization with CTABr (cetyl trimethyl ammonium bromide) as the clay galleries' organomodifier. In terms of the PANI-Mag ratio, the electrical and thermal properties of the obtained nanocomposites are investigated. As the amount of Maghnite in the nanocomposite increases, thermal stability improves noticeably, as measured by thermal gravimetric analysis. The electric conductivity of nanocomposites is lower than that of free PANI. As the device is loaded with 5 % clay, the conductivity begins to percolate and decreases by many orders of magnitude. The findings show that the conductivity of nanocomposites is largely independent of clay loading and dispersion.

Abstract:

Abstract Low-linear density (LDPE) and copper (Cu) were used as main polymer matrix and conductive filler in order to produce electrically conductive polymer composites (CPC). The selection of the matrix and conductive filler were based on their due to its excellence properties, resistance to corrosion, low cost and electrically conductive. This research works is aimed to establish the effect of compounding parameter on the electrical conductivity of LDPE/Cu composites utilising the design of experiments (DOE). The CPCs was compounded using an internal mixer where all formulations were designed by statistical software. The scanning electron micrograph (SEM) revealed that the Cu conductive filler had a flake-like shape, and the electrical conductivity was found to be increased with increasing filler loading as measured using the four-point probe technique. The conductivity data obtained were then analysed by using the statistical software to establish the relationship between the compounding parameters and electrical conductivity where it was found based that the compounding parameters have had an effect on the conductivity of the CPC.

Abstract:

The intrinsic electrical conductivity of graphene is one of the key factors affecting the electrical conductance of its assemblies, such as papers, films, powders, and composites. Here, the local electrical conductivity of the individual graphene flakes was investigated using conductive atomic force microscopy (C-AFM). An isolated graphene flake connected to a pre-fabricated electrode was scanned using an electrically biased tip, which generated a current map over the flake area. The current change as a function of the distance between the tip and the electrode was analyzed analytically to estimate the contact resistance as well as the local conductivity of the flake. This method was applied to characterize graphene materials obtained using two representative large-scale synthesis methods. Monolayer graphene flakes synthesized by chemical vapor deposition on copper exhibited an electrical conductivity of 1.46 ± 0.82 × 106 S/m. Reduced graphene oxide (rGO) flakes obtained by thermal annealing of graphene oxide at 300 and 600 °C exhibited electrical conductivities of 2.3 ± 1.0 and 14.6 ± 5.5 S/m, respectively, showing the effect of thermal reduction on the electrical conductivity of rGO flakes. This study demonstrates an alternative method to characterizing the intrinsic electrical conductivity of graphene-based materials, which affords a clear understanding of the local properties of individual graphene flakes.

It is established that the introduction of 10–20 wt. % carbon black in linear low-density polyethylene provides high conductivity of composite materials, while increasing their modulus of elasticity, but at the same time reduces elongation at break. It is shown that, in general, the studied carbon black is a promising filler in the development of electrically conductive polymer composite materials for electrical and radio engineering purposes.

Abstract:

This Extrusion permit in controlling electrical conductivity before composite materials undergo the manufacturing process. However, studies on electrical conductivity in high conductive polymer composite materials are still in preliminary stage. Thus, the studies on electrical conductivity model are crucial as it able in predicting the electrical conductivity hence minimizing the experimental conducted. In this study, conductivity model was conducted to validate the series of experiment. The electrical conductivity increases as shear rate decrease and the highest electrical conductivity of 3 S/cm is obtained which indicated that the shear rate is crucial in increasing the electrical conductivity of the composites compared to extrusion temperature hence it is consider in the modelling.

Abstract:

Using the example of fabrics and knitwear from a mixture of natural and synthetic polymer fibers, the possibility of obtaining polymer compositions intended for the manufacture of electrically conductive elements for aviation, robotics and so-called "wearable electronics" for medical purposes is shown. The mechanical and electrical properties of fibrous compositions filled with carbon dispersions in various allotropic forms in combination with both soluble and insoluble high-molecular compounds in the form of powders or solutions have been studied. Dispersions of various forms of carbon with a close particle size distribution were selected from among commercially available brands of printing pigments and ingredients of rubber and electrical products. Carbon dispersions were investigated: graphite, carbon black and single-walled nanotubes in the form of a stabilized aqueous suspension. The well-known and justified optimal technological methods of introducing electrically conductive ingredients into the composition of composite materials, taking into account the structure and composition of fabrics. The advantage of spraying electrically conductive graphite particles on the surface of fibers and filaments in combination with the application of solutions and dispersions is shown, which makes it possible to obtain compositions for resistors and strain sensors with a sufficient level of strength and elasticity. The stretching diagram of the sensors and the dependence of the electrical resistance of the composition on the elongation with a high degree of confidence can be divided into two linear sections. The first section in the range of relative tensile strain from 2 to 30% is most consistent with practical application. The coefficient of sensitivity to deformation (GF) of a fabric-based strain gauge does not exceed 10 in the range of deformation in the diagonal direction up to 20%, and the coefficient of sensitivity to deformation on knitwear, regardless of the direction of cutting samples from the canvas, is two orders of magnitude higher and is about 950 to a relative elongation of 30% and 90 in the range of a relative elongation of 30÷45%. The maximum strain sensitivity (QF) of laboratory samples based on knitted fabric, with a deformation of less than 30%, is about 1350 kPa-1 and 4900 kPa-1 at maximum elongation%. The hysteresis of electrical properties with multiple deformations does not exceed 4%.

Abstract:

The present work reports the production and characterization of polyetheretherketone (PEEK) nanocomposite filaments incorporating carbon nanotubes (CNT) and graphite nanoplates (GnP), electrically conductive and suitable for fused deposition modeling (FDM) processing. The nanocomposites were manufactured by melt mixing and those presenting electrical conductivity near 10 S/m were selected for the production of filaments for FDM. The extruded filaments were characterized for mechanical and thermal conductivity, polymer crystallinity, thermal relaxation, nanoparticle dispersion, thermoelectric effect, and coefficient of friction. They presented electrical conductivity in the range of 1.5 to 13.1 S/m, as well as good mechanical performance and higher thermal conductivity compared to PEEK. The addition of GnP improved the composites’ melt processability, maintained the electrical conductivity at target level, and reduced the coefficient of friction by up to 60%. Finally, three-dimensional (3D) printed test specimens were produced, showing a Young’s modulus and ultimate tensile strength comparable to those of the filaments, but a lower strain at break and electrical conductivity. This was attributed to the presence of large voids in the part, revealing the need for 3D printing parameter optimization. Finally, filament production was up-scaled to kilogram scale maintaining the properties of the research-scale filaments.

Abstract:

AbstractThe conductivity of La-montmorillonite was measured in the domain of water relative pressures (p/p0) of <1, and compared with the conductivites of Li- and Na-montmorillonite. La-montmorillonite shows smaller conductivity over the whole range of p/p0 studied. To explain this, theoretical considerations of the polarizing power and of the local stacking order induced by the exchangeable cation were addressed.
