Résumé :

A polyurethane (PU) is a multifunctional polymer prepared by using more than two types of monomers. The unique properties of PU come from monomers, thus broadening the applicability of PU in many different sectors. The properties can be further improved by using many nanoparticles. Different metal oxides as nanoparticles are also widely used in PU materials. ZnO is a widely used inorganic metal oxide nanoparticle for improving polymer properties. In this review article, the techniques to prepare a PU/ZnO composite are reviewed; the key protective properties, such as adhesive strength and self-healing, and applications of PU/ZnO composites are also highlighted. This review also highlights the PU/ZnO composite’s current challenges and future prospects, which will help to broaden the composite practical application by preparing environmentally friendly composites.

Résumé :

Polymer blend or composite, which is a combination of two or more polymers and fillers such as semiconductors, metals, metal oxides, salts and ceramics, are a synthesized product facilitating improved, augmented or customized properties, and have widespread applications for the achievement of functional materials. Polymer materials with embedded inorganic fillers are significantly appealing for challenging and outstanding electric, dielectric, optical and mechanical applications involving magnetic features. In particular, a polymer matrix exhibiting large values of dielectric constant (ε′) with suitable thermal stability and low dielectric constant values of polymer blend, having lesser thermal stability, together offer significant advantages in electronic packaging and other such applications in different fields. In this review paper, we focused on the key factors affecting the dielectric properties and its strength in thin film of inorganic materials loaded poly methyl meth acrylate (PMMA) based polymer blend (single phase) or composites (multiple phase), and its consequences at low and high frequencies are explored. A wide range of different types of PMMA based polymer blends or composites, which are doped with different fillers, have been synthesized with specific tailoring of their dielectric behavior and properties. A few of them are discussed in this manuscript, with their different preparation techniques, and exploring new ideas for modified materials.

Résumé :

Introduction of magnetic nanoparticles into composite sorbents based on polymer matrices has received great attention due to the possibility of using cheap iron oxides and removing spent sorbents by means of magnetic separation. In the present paper, we discuss the problem of creating magnetic sorbents using two types of matrices as host materials: synthetic cation exchange resin and natural aminopolysaccharide chitosan. The possibilities of applying matrices for the in situ formation of oxide phases of a specified composition with the required content of an inorganic component in a composite material were estimated. The composition of the oxide phase formed in the composite material was studied, and particle sizes were evaluated by the method of X-ray diffraction analysis. Magnetic characteristics were investigated. Sorption characteristics with respect to strontium for the composites containing iron oxides were determined.

Résumé :

Purpose. Evaluation influence structural state polymer phase on the response voltage and coefficient nonlinearity of a multilayer varistor based on zinc oxide. Methodology. Zinc oxide consisted of 97% zinc oxide and 3% total oxides of Bi2O3, Co3O4, MnO2, B2O3, SbO3, ZrO2, Al2O3. At a temperature of 1573°K, the synthesis of semiconductor ceramics based on Zinc oxide was carried out. For composite of thermoplastic polymers and Zinc oxide, non-polar and polar polymers, high pressure polyethylene and polyvinylidene fluoride were used. The composites were obtained by hot pressing at the melting temperature of the polymer phase and a pressure of 15 MPa. After that, using silver paste, measuring electrodes 10 mm in diameter were applied to the surface of the synthesized samples, and then current–voltage characteristics were measured. Modification of composites under action of gas-discharge plasma was carried out in a special cell that creates a dielectric-gas-composite system. The structure of the composites was studied by X-ray diffraction analysis and IR spectroscopy. Findings. The obtained experimental results show that the size of the particles of the inorganic phase significantly affects the current-voltage characteristics of the composite varistor: at a given thickness of the composite varistor, the operation voltage decreases markedly, and the nonlinearity coefficient increases. Numerous experimental results obtained by us show that the impact of electric discharge plasma on the polymer Zinc oxide-composite leads to a significant change in the permittivity and the concentration of local levels at the interface of the composite. The results research showed that effect electrical plasma on the opening voltage depends on the polarity of polymer matrices. Moreover, plasma processing itself significantly changes the structure of the polymer phase at composite. Originality. The magnitude of the potential barrier at phase boundary is mainly determined by the volume fraction and size of the main structural element of ZnO ceramics. Changing the structural state of the polymer matrix allows the adjust response voltage and coefficient nonlinearity of volt-ampere characteristic of the multilayer varistor. Practical value. The discovered development of electron-ion processes at polymer phase of the varistor indicates the need to take into account change in its service characteristics from the duration and intensity of use. The result obtained has a certain practical significance, since it indicates not only the reason for the change in properties, but also the need to develop measures to increase the service life of the varistor.

Résumé :

The rapid development of conductive polymers shows great potential in temperature chemical gas detection as their electrical conductivity is often changed upon spotlight to oxidative or reductive gas molecules at room temperature. However, the relatively low conductivity and high affinity toward volatile organic compounds and water molecules always exhibit low sensitivity, poor stability and gas selectivity, which hinder their practical gas sensor applications. In addition, inorganic sensitive materials show totally different advantages in gas sensors like high sensitivity, fast response to low concentration analytes, high area and versatile surface chemistry, which could harmonize the conducting polymers in terms of the sensing individuality. It seems to be a good option to combine inorganic sensitive materials with polymers for gas detection for the synergistic effects which has attracted extensive interests in gas sensing applications. In this appraisal the recapitulation of recent development in polymer inorganic nanocomposites-based gas sensors. The roles of inorganic nanomaterials in improving the gas sensing performances of conducting polymers are introduced and therefore the progress of conducting polymer inorganic nanocomposites including metal oxides, metal, carbon (carbon nanotube, graphene) and ternary composites are obtainable. Finally, conclusion and perspective within the field of gas sensors incorporating conducting polymer inorganic nanocomposites are summarized. Keywords: Gas sensor, conducting polymer, polymer-inorganic nanocomposites; conducting organic polymers nanostructure, synergistic effect, polypyrrole (PPY), polyaniline (PANI).

Résumé :

Abstract In the past few years, there was a tremendous growth in conjugated polymer nanofibers via design of novel conjugated polymers with inorganic materials. Synthetic routes to these conjugated polymers involve new, mild polymerization techniques, which enable the formation of well-defined polymer architectures. This review provides interest in the development of novel (semi) conducting polymers, which combine both organic and inorganic blocks in one framework. Due to their ability to act as chemosensors or to detect various chemical species in environmental and biological systems, fluorescent conjugated polymers have gained great interest. Nanofibers of metal oxides and sulfides are particularly interesting in both their way of applications and fundamental research. These conjugated nanofibers operated for many applications in organic electronics, optoelectronics, and sensors. Synthesis of electrospun fibers by electrospinning technique discussed in this review is a simple method that forms conjugated polymer nanofibers. This review provides the basics of the technique and its recent advances in the formation of highly conducting and high-mobility polymer fibers towards their adoption in electronic application.

Résumé :

Here, we discuss the fabrication and problems of application of chitosan-based composite materials for the removal of hazardous metal ions from tap water and wastewater. The chitosan-based composites containing iron oxides for the uptake of Sr2+ ions were fabricated via a co-precipitation method with variation of the iron/chitosan ratio and pH of the medium. The morphology and composition of the fabricated sorbents were characterized using scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM–EDX) and X-ray diffraction (XRD) analysis. We have shown that the suggested fabrication approach allows for a homogeneous distribution of the inorganic phase in the polymer matrix. Investigations of the sorption performance of the composites have shown that they are efficient sorbents for 90Sr radionuclides uptake from tap water. The composite sorbent containing amorphous iron oxide in a chitosan matrix and calcined at 105 °C showed the best sorption characteristics. We have also demonstrated that there is an optimal iron oxide content in the composite: with increasing oxide content, the efficiency of the sorbents decreases due to poor stability in solution, especially in alkaline media. The alternative approach yielding magnetic chitosan-based composites with sufficiently good sorption performance and stability in neutral and weakly alkaline media is suggested.

Résumé :

Gas sensing materials, such as semiconducting metal oxides (SMOx), carbon-based materials, and polymers have been studied in recent years. Among of them, SMOx-based gas sensors have higher operating temperatures; sensors crafted from carbon-based materials have poor selectivity for gases and longer response times; and polymer gas sensors have poor stability and selectivity, so it is necessary to develop high-performance gas sensors. As a porous material constructed from inorganic nodes and multidentate organic bridging linkers, the metal-organic framework (MOF) shows viable applications in gas sensors due to its inherent large specific surface area and high porosity. Thus, compounding sensor materials with MOFs can create a synergistic effect. Many studies have been conducted on composite MOFs with three materials to control the synergistic effects to improve gas sensing performance. Therefore, this review summarizes the application of MOFs in sensor materials and emphasizes the synthesis progress of MOF composites. The challenges and development prospects of MOF-based composites are also discussed.

Résumé :

In recent years, polymer-inorganic nanoparticle compositions have been a subject of considerable interest in order to achieve desired chemical, physical properties and mechanical properties. In this study a polymer nanocomposites have been prepared by incorporating silica nanoparticles (~20 nm) as fillers into poly(ethylene oxide) matrix. The composites of poly(ethylene oxide) and silica nanoparticles were prepared by solution blending. The product composites were powders. The thermal properties of the composites were investigated using the Differential Scanning Calorimetry. The Nuclear Magnetic Resonance (13C solid state, T1ρ), Atomic Force Microscopy, X-ray diffraction and Fourier Transform Infrared Spectroscopy were used to investigate the effect of the nanoparticles on the polymer matrix. The results suggest that the silica nanoparticles were reasonably well dispersed in the PEO 35K. The dispersion was accompanied by slightly reduced the crystallinity. However, with increasing the SiO2 nanoparticles the aggregation Phenomenon appears. Moreover, with increase in the MW of the PEO to 100K the dispersion of the nanoparticles decreased and aggregation phenomenon is observed even at lower of SiO2 contents.

Résumé :

A versatilidade das espumas poliuretanas permite sua aplicação em inúmeros setores industriais, devido à possibilidade de se obter diferentes conjuntos de propriedades apenas alterando sua formulação básica. Um tipo recorrente de alteração é a incorporação de diferentes tipos de fibras em matrizes de poliuretano, vastamente estudada com o objetivo de gerar materiais compósitos com melhores propriedades mecânicas do que a matriz original. Inúmeros autores reportaram a utilização de celulose cristalina como uma alternativa renovável aos agentes de reforço e revelaram que a celulose utilizada como aditivo em matrizes poliméricas afetou as propriedades mecânicas da matriz original e, em menor escala, exerceu influência sobre a estabilidade térmica do compósito. O presente trabalho dedicou-se a isolar a celulose cristalina contida nas fibras de bananeira mediante tratamento com ácido acético concentrado. Os tratamentos químicos são necessários para modificar a superfície do material e melhorar a adesão do agente de reforço à matriz. Tendo em vista os resultados associados à estabilidade térmica dos compósitos de poliuretano reforçados com celulose, buscou-se sintetizar materiais híbridos de celulose e MgO.nH2O. Foi observado que, mesmo em pequenas quantidades, a presença do óxido hidratado de magnésio afetou significativamente a estabilidade térmica do HB 98:2. Estudos térmicos indicam que os materiais compósitos estudados apresentaram comportamento semelhante ao da matriz PU. Estudos das propriedades compressivas dos materiais poliméricos gerados mostraram que a incorporação do HB 98:2 ao PU afetou positivamente as propriedades mecânicas do material, sendo que o compósito PU + 1 HB 98:2 apresentou desempenho mecânico superior ao da matriz pura.
The versatility of polyurethanes foams allows its application in numerous industries because of the possibility of obtaining different sets of properties just by changing its basic formulation. A recurrent type of modification is the incorporation of different types of fibers in polyurethane matrices widely studied with the objective of generating composite materials with better mechanical properties than the original matrix. Numerous authors have reported the use of crystalline cellulose as a renewable alternative to fillers and showed that the cellulose used as additive in polymer matrices affect the mechanical properties of the original matrix and, to a lesser extent, influence upon thermal stability of the composite. This work was dedicated to isolate the crystalline cellulose contained in banana fibers by treatment with concentrated acetic acid. The chemical treatments are needed to modify the surface of the material and improve adhesion of the filler to the matrix. In view of the results associated with the thermal stability of the composite polyurethane reinforced with cellulose, sought to synthesize hybrid materials cellulose and MgO.nH2O. It has been observed that even in small quantities, the presence of hydrated magnesium oxide significantly affect the thermal stability of HB 98: 2. thermal studies indicate that the studied composites showed similar behavior to the PU matrix. Studies of the compressive properties of polymeric materials generated showed that the incorporation of HB 98: 2 to PU positively affect the mechanical properties of the material, and the composite PU + HB 98 1: 2 had mechanical performance superior to that of pure matrix.

Résumé :

A knowledge of structure is crucial to the understanding of inorganic solids and polymers. Neutron and X-ray powder diffraction are two powerful complementary techniques which can be used in the structural characterisation of a variety of crystalline materials. Chemical and electrochemical oxygen intercalation techniques involving both aqueous and non-aqueous systems, have been investigated for a number of crystalline inorganic oxides. The pyrochlore structure has been discovered to be a new class of host for the chemical intercalation of oxygett and the interstitial solid solution of Ce2Zr2O7+x based on this structure-type has been investigated. Intercalation in this system is found to involve an unusual mechanism of oxygen displacement. The structures of other complex metal oxides have also been elucidated using a combination of X-ray and neutron powder diffraction, including those of Li29Zr9Nb3O40 and Li29Zr9.6Ta2.4O40. The doping behaviour of magnesium into the technologically important material lithium niobate has also been studied using these techniques. Polymer electrolytes are a class of ionically conducting solid phases formed by the dissolution of salts in ion co-ordinating macromolecules. The relationship between the crystalline and amorphous phase of the polymer-salt complex PEO3.LiCF3SO3 has been examined by variable-temperature powder X-ray diffraction. This has shed new light on the relationship between the crystalline and amorphous structures of polymer electrolytes. Finally, the crystal structure of the polymer-salt complex PEO4:RbSCN has been determined.

Résumé :

This thesis describes an investigation of various polymer/nanotube composite systems, using computer simulation. Firstly, pure polymer melts composed of linear homopolymers, polyethylene (PE) and poly(ethylene oxide) (PEO), were studied by a multiscale modelling approach. A Monte Carlo coarse-grained lattice model was employed to generate initial equilibrated chain configurations. A process of ‘reverse-mapping’ was then used to recover atomistic details from the coarse-grained model. After that, fully atomistic molecular dynamic (MD) simulations have been performed on samples of PE and PEO melts. Our results suggest good agreement of structural and dynamical properties between current MD results and experimental and theoretical results. Next, we discussed the application of this multiscale modelling approach to the study of PE/CNT (carbon nanotube) composite system. The presence of CNT causes a clear structuring of the polymer chains around the nanotube surface. Furthermore, structural relaxations of the interfacial PE chains were found to be slower than that of the pure PE melt. MD method and effective fibre theory were used for the calculation of composite mechanical properties, and results agree with experimental data. Finally, we attempted to study the organic/inorganic interface. A composite model containing an inorganic TiO₂ nanotube embedded in a PEO matrix was generated and results are compared with the PEO/CNT system. Much stronger structuring and ordering of PEO chains were found in the vicinity of the TiO₂ surface. In addition, the PEO conformation was more coiled in order to better adapt to the TiO₂ nanotube. Evidence for chain immobilization is more obvious in the PEO/TiO₂ system, which contributes to the improvement of interfacial properties of the composite.

Résumé :

A study has been undertaken with the aim of preparing appropriately functionalised polyhedral oligomeric silsesquioxane (POSS) compounds to be used in ambient-cure chemistry. Numerous epoxy-functionalised compounds have been designed and synthesised and these materials have been characterised in order to determine their chemical structure. These compounds have also been incorporated into existing polymerisation reactions to test whether these materials could be used in the protective coatings industry. A glycidyl-functionalised POSS compound was prepared and reacted with a series of amines to produce ambient-cured polymers which could be used in the coatings industry. There were also a series of experiments undertaken on these polymers to identify the processes at work and to test how they compare to industry standards. As a direct comparator to this work, another set of results was obtained with a cyclic-siloxane material incorporated into the systems in place of the POSS. A linear analogue was also tested. The reactions proved to be a success and an appropriate data-set was yielded. During the synthesis of POSS precursors there are a series of residual materials produced. These materials have also been studied in this project. It was anticipated that these would behave in a similar way to the POSS compounds however the same functionality was never achieved as had been with the POSS. Ambient-cured polymers have also been targeted from a basic hydride-functionalised POSS compound and a polybutadiene system. The appropriate reactions unfortunately never took place as anticipated but there were a series of tests undertaken to identify the processes at work. A study has also been undertaken using near-I.R. to track the curing reactions. From this data, the extent of cure could be studied and the make-up of the reaction could be investigated in more detail.

Résumé :

The combination of organic and inorganic materials forms unique composites with properties that neither of the two components provides. Such functional materials are considered innovative advanced materials that enable applications in many fields, including optics, electronics, separation membranes, protective coatings, catalysis, sensors, biotechnology, and others. The challenge of incorporating inorganic particles into an organic matrix still remains today, especially for nanoparticles, due to the difficulties in their dispersion, de-agglomeration and surface modification. NanoGram has pioneered a nanomaterials synthesis technology based on laser pyrolysis process to produce a wide range of crystalline nanomaterials including complex metal oxides, nitrides and sulfides and with precisely controlled compositions, crystal structure, particle size and size distributions. In this paper we will present some examples of nanocomposites prepared using different polymer host materials and phase-pure rutile TiO2. The inorganic component can be dispersed at higher 50 weight percent into the polymer matrix. We have demonstrated a 0.2–0.3 increase of refractive index in the composite over that of host polymer while maintaining high optical transparency. These nanocomposites can be used in a range of applications or optical devices, such as planar waveguides, flat panel displays, optical sensors, high-brightness LEDs, diffraction gratings and optical data storage. Experimental data on TiO2 nanoparticle characterization, dispersion technique, surface modification and will be presented and nanocomposite properties discussed.

Résumé :

Methacrylate and acrylate terminated monomers can be rapidly polymerized to polymer glasses useful in biomaterials, photolithography and rapid prototyping, optical coatings and composites. Unfortunately, polymerization shrinkage results in loss of tolerance and the development of internal stresses which can be especially critical in the case of highly crosslinked glasses. Structurally complicated oligomeric mixes of dimethacrylate monomers that exhibit a nematic liquid crystal to isotropic transition above room temperature have been synthesized in a low cost one pot synthesis to surmount the problem of polymerization shrinkage and the propensity of single component monomers to crystallize from the liquid state. Photopolymerization from the ordered liquid crystal state into a less ordered glass minimizes volumetric shrinkages to between 1–2% at greater than 90% polymerization conversion. These polymer glasses exhibited elastic bending moduli of 1.2 GPa to 1.5GPa, fracture strengths of 70–100MPa and fracture toughness of K=0.3–0.4 (MPa)1/2. In some cases the glasses exhibited ductile behavior which is unusual for highly crosslinked materials. Room temperature viscosities of 100P–2000P permit facile processing of the liquid crystal monomers with inorganic particles to make dental restorative composites.

Résumé :

Mechanoluminescence (ML) is a property of inorganic and organic materials that describes the emission of light due from the application of force. Inorganic crystals (mostly phosphors) and certain organic macromolecules exhibit elastico-ML and are a natural fit for structural health monitoring (SHM) of composite structures. Composites with particulate ML crystals enable the visualization of stress distribution over a plane and over contoured surfaces in a spatially continuous manner. Imaging ML composites with affordable high-resolution imaging methods further enables the creation of high-resolution validation method for computational methods. Also, with the embedding of suitable photo-detectors for signal detection, the need for additional wiring, sensor electronics and high-level electronics is eliminated. In this conference proceedings technical publication, the application of commercially available ZnS:Cu, Mn phosphors for SHM of polymer composites will be presented via experimental and structural simulation. Results demonstrate the dependence of intensity of elastico-ML (in cd/cm2) on strain rate, strain and composition (w/w of ML particulates). The experiments show methods to fabricate elastic coupons of phosphors in polydimethylsiloxane (PDMS) and subsequent methods for application in SHM. The structures are excited at 5Hz to 17.5Hz to develop empirical relationships between strain rate and EML intensity and it is shown that the intensity increases nonlinearly with the magnitude of stress/strain rate. A range of stresses transferred to the EML particles by the PDMS matrix is also numerically predicted. The numerical simulations show the importance of interfacial binding in the transfer of stress and subsequent EML emission. These results also provided a basis for validation and improvement of structural simulation models.

Résumé :

During the past decade, the preparation of inorganic/organic hybrid materials with high refractive index has attracted considerable attention. In particular, TiO2 (Titanium dioxide or Titania), as inorganic domains, have been incorporated into a polymer matrix to produce high refractive index hybrid materials [1–3]. Polarization of injection molded liquid crystal polymer/Titania composite parts have been investigated in the broad band millimeter wave frequency range. The measurements have been performed by using two different spectroscopy techniques. First, free space quasi optical millimeter wave spectrometer, equipped with a high power source coherent radiation tunable in the 40–90 GHz frequency range is used. Second, low power dispersive Fourier transform spectrometer has been used for higher frequencies in the range of 100–600 GHz. Dielectric properties of liquid crystal polymer/Titania composites have been determined in the broad band millimeter wave frequency range. A correlation between dielectric properties and dispersed Titania weight percent has been observed using the two spectroscopy techniques. It is found that the absorption coefficient and loss tangent is a strong function of the output power of the sources of the incident radiation. On the other hand, refractive index and real permittivity values measured from both spectroscopy techniques are similar. In addition, it has been found that transmittance level and absorption losses depend on the orientation of the samples with respect to the orientation of electric and magnetic fields in the incident electro-magnetic wave. Finally, the polarization of the parts varies with the direction of flow of the molten plastic into the cavity.
