TL;DR: These findings indicate that adding colloidal silica to higher breakdown strength amorphous polymers causes a reduction in dielectric strength as compared to the neat polymer, and that at these loadings failure becomes independent of polymer matrix and is dominated by silica.
Abstract: The ultimate energy storage performance of an electrostatic capacitor is determined by the dielectric characteristics of the material separating its conductive electrodes. Polymers are commonly employed due to their processability and high breakdown strength; however, demands for higher energy storage have encouraged investigations of ceramic–polymer composites. Maintaining dielectric strength, and thus minimizing flaw size and heterogeneities, has focused development toward nanocomposite (NC) films; but results lack consistency, potentially due to variations in polymer purity, nanoparticle surface treatments, nanoparticle size, and film morphology. To experimentally establish the dominant factors in broad structure–performance relationships, we compare the dielectric properties for four high-purity amorphous polymer films (polymethyl methacrylate, polystyrene, polyimide, and poly-4-vinylpyridine) incorporating uniformly dispersed silica colloids (up to 45% v/v). Factors known to contribute to premature b...

TL;DR: In this article, two and three-phase Lewis-Nielsen models are proposed for fitting the experimental values of the thermal conductivity of epoxy-based polymer composites, and the properties of the interfacial zone between the host polymer and the surface modified nanoparticles.
Abstract: In this paper the thermal conductivity of epoxy-based composite materials is analysed. Two and three-phase Lewis–Nielsen models are proposed for fitting the experimental values of the thermal conductivity of epoxy-based polymer composites. Various inorganic nano- and microparticles were used, namely aluminium oxide, aluminium nitride, magnesium oxide and silicon dioxide with average particle size between 20 nm and 20?m. It is shown that the filler–matrix interface plays a dominant role in the thermal conduction process of the nanocomposites. The two-phase model was proposed as an initial step for describing systems containing 2 constituents, i.e. an epoxy matrix and an inorganic filler. The three-phase model was introduced to specifically address the properties of the interfacial zone between the host polymer and the surface modified nanoparticles.

TL;DR: In this paper, a liquid crystalline polymer (LCP) poly(benzoyl-1,4-phenylene)-co-(1,3)-phenylene nanocomposite was prepared with exfoliated graphene nanoplatelets (GnP) to achieve both high mechanical modulus and electrical conductivity.
Abstract: A liquid crystalline polymer (LCP) poly(benzoyl-1,4-phenylene)-co-(1,3-phenylene)], nanocomposite was prepared with exfoliated graphene nanoplatelets (GnP) to achieve both high mechanical modulus and electrical conductivity. The fabrication technique and the dispersion of nanoplatelets have been shown to be critical to achieve high mechanical modulus at low filler loading. A loading of only 1 vol.% of the GnP particles improved the modulus of the LCP nanocomposite by 25% and 55% at a loading of 5 vol.%. The electrical conductivity the non-conductive LCP improved to a very high value of 4.5 × 10 −4 S/cm with the addition of 5 vol.% of GnP nanoparticles.
