Abstract

The transport mechanism in Poly(ethylene)-graphite composites has been investigated through the analysis of the dc conductivity and complex permitivity in the 10²–10⁷ Hz frequency range. The study of this relatively simple system can be useful for the interpretation of transport in composite materials of higher complexity. A description of the transport mechanism in terms of tunneling conduction between adjacent particles is proposed to explain the observed experimental behaviour. Such a mechanism can be responsible for the observed dc conductivity deviations from the percolation theory predictions at low graphite concentrations.

Polymer-graphene composite in aerospace engineering
2021, Polymer Nanocomposites Containing Graphene: Preparation, Properties, and Applications
Currently, polymer nanocomposites are occupying a major domain in high performance lightweight materials. Fiber reinforced polymer composites always remain in the first row among all the composite materials because of their high Young’s modulus and strength to weight ratio with respect to conventionally used metallic components for aerospace material. However, over the last few years, the motivation has been concentrated in the direction of nanocomposites material to improve longevity, and fuel efficiency of the aircrafts. This chapter focuses on the current status of research on the properties and applications of graphene-based polymer composite structures used in aerospace engineering. The polymers and fillers used in aerospace applications; the reason for graphene and its derivatives suitability in aerospace engineering were also illustrated.

Graphite provides conductive path and high surface area to PPy composite materials and furthermore, from the literature survey, it was seen that graphite possess very good electrical conductivity, thermal and mechanical properties. Because of its superior properties once graphite is incorporated to PPy matrix it is expected to improve the strength and other properties of PPY/graphite nanocomposites [36–38]. EMI shielding and microwave property of conducting polymer composite materials are receiving vast attention to safeguard electronic circuits, electronic gadgets, electronic instrumentation and also environment in academic, health care, research, commercial, industrial and defense sectors in the microwave frequency range from 8 to 18 GHz spectrum [39].
Synthesis of polypyrrole (PPy) / graphite (G) composites via chemical oxidation polymerization method is reported. Synthesized composites were studied for its structural, optical and electrical properties. Structural and morphological studies were performed using powder X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and the effect of graphite on the properties of PPy is elaborated in detail. Further, the electrical measurements were carried using dielectric analyzer. Dielectric behavior of the composites was also compared with the PPy and graphite and confirmed the dependency of graphite on PPy/graphite nanocomposites. The EMI shielding response of PPy/graphite nanocomposites were measured in the microwave frequency range from 12 to 18 GHz (Ku band), of practical relevance. The observed effective electrical and EMI shielding properties highlights the prospects of multifunctional applications of these PPy/graphite nanocomposites.
Effect of zirconium oxide nanopowder on the thermal, chemical and gas barrier properties of starch
2014, Materials Science in Semiconductor Processing
Starch/zirconium oxide (Starch/ZrO₂) bionanocomposites were prepared using various percentages of nano-ZrO₂ by a solution technique. The interaction of ZrO₂ nanocomposites with starch was studied by Fourier transform infrared spectroscopy (FTIR) and their structural behavior was investigated by X-ray diffraction (XRD). The dispersion of ZrO₂ within virgin starch was investigated by a field emission scanning electron microscope (FESEM), a high resolution transmission electron microscope (HRTEM) and selected area electron diffraction (SAED). Thermal properties of starch/ZrO₂ bionanocomposites were studied by thermogravimetric analysis (TGA). An increase in thermal stability was observed with increase in filler loading. The conductivity of starch/ZrO₂ bionanocomposites was measured and an increase in conductivity was observed due to the increase in ZrO₂ concentration. Starch/ZrO₂ bionanocomposites were more resistant towards chemicals like dilute acid and alkali. The oxygen barrier property of composites was studied and a substantial reduction in permeability was observed. Further, the biodegradability of starch/ZrO₂ bionanocomposites was reduced. Thermally stable, chemical resistant, and gas barrier starch bionanocomposites with conducting property may enable the materials for manufacturing packaging materials and semiconducting devices.
Dispersion of ZrO<inf>2</inf> nanoparticles in polyacrylonitrile: Preparation of thermally-resistant electrically-conductive oxygen barrier nanocomposites

A unique feature of polymer nanocomposites is that a dramatic improvement of properties is reached at low filler content. Conducting fillers including natural flake graphite, carbon black and metal powder to prepare electrically conducting composites has attracted great interest for decades [4,5]. The conductivity of nanocomposites depends on the loading of conducting fillers.
Polyacrylonitrile/zirconium dioxide (PAN/ZrO₂) nanocomposites were synthesized by dispersion of ZrO₂ nanoparticles through the in situ emulsifier-free emulsion polymerization technique. The thermal stability of PAN/ZrO₂ nanocomposites was enhanced with increasing concentrations of ZrO₂ which may be due to dispersion of nanoparticles in PAN matrix. The electrical conductivity of nanocomposites gradually increased with increase in the ZrO₂ loading. The gas barrier property of PAN/ZrO₂ nanocomposites was determined by using gas permeameter and it was found that, the gas barrier property was reduced to about 10 times with increase of ZrO₂ proportions. This is because ZrO₂ nanoparticles in PAN/ZrO₂ nanocomposites created a tortuous path for preventing oxygen permeation. The electrical conductive PAN/ZrO₂ nanocomposites may be used in semiconductor devices and packaging materials.
Effect of expanded graphite on thermal, mechanical and dielectric properties of ethylene-propylene-diene terpolymer/hexa fluoropropylene- vinylidinefluoride dipolymer rubber blends

Blending a polymer with conducting fillers, such as natural graphite flake, carbon black, and metal powders, to prepare electrically conducting composites has been extensively investigated in the past few decades. Among the various conducting fillers, naturally abundant graphite, which possesses good electrical conductivity of about 104 S/cm at ambient temperature, has been widely used [3,4]. In most cases, relatively large quantities of graphite were needed to reach the critical percolation value, as the graphite particle size is at micrometer and millimeter scale.
Expanded graphite (EG) filled with compatibilized and uncompatibilized EPDM/FKM (50/50, w/w) blends were prepared by two-roll mill mixing. Maleic anhydride grafted EPDM (MA-g-EPDM) is used as a compatibilizer. The cure characteristics, filler dispersion, mechanical properties and DC electrical conductivity of the composites were evaluated. The thermal stability of the EG loaded EPDM/FKM blends was studied using thermogravimetric analysis (TGA). The activation energy of the composites was evaluated by the Coats–Redfern method. The microwave properties like dielectric permittivity, dielectric loss, conductivity, dielectric heating coefficient and absorption coefficient were evaluated. At higher EG loading, the optimum cure time (T₉₀) decreases due to the increased thermal transition of the blends in presence of EG. The tensile properties of all the composites, especially those with compatibilizer, increased with aging. The AC and DC conductivities increase with increase in EG loading, due to the formation of enhanced conductive networks by EG platelets. The flammability and thermal characteristics are improved by the addition of EG. The morphology of the composites was investigated using scanning electron microscopy (SEM).
