“…Storage modulus of a material shows a measure of stiffness, or in other words, it is a measure of material elastic behavior. A. Permal et al found that increase in filler loading shows enhancement in storage modulus and significant reduction in T g . The same authors analyzed the effect of bimodal filler on thermal and mechanical properties of composites.…”

Ever since the discovery of polymer composites, its potential has been anticipated for numerous applications in various fields such as microelectronics, automobiles, and industrial applications. In this paper, we review filler reinforced polymer composites for its enormous potential in microelectronic applications. The interface and compatibility between matrix and filler have a significant role in property alteration of a polymer nanocomposites. Ceramic reinforced polymeric nanocomposites are promising candidate dielectric materials for several micro‐ and nano‐electronic devices. Because of its synergistic effect like high thermal conductivity, low thermal expansion, and dielectric constant of ceramic fillers with the polymer matrix, the resultant nanocomposites have high dielectric breakdown strength. The thermal and dielectric properties are discussed in the view of filler alignment techniques and its effect on the composites. Furthermore, the effect of various surface modified filler materials in polymer matrix, concepts of network forming using filler, and benefits of filler alignment are also discussed in this work. As a whole, this review article addresses the overall view to novice researchers on various properties such as thermal and dielectric properties of polymer matrix composites and direction for future research to be carried out.

“…A traditional method is chemical grafting of a silane coupling agent to polymer chains and filler particles. Permal et al 14 functionalized Al 2 O 3 nanoparticles and BN nanoplatelets with (3-aminopropyl)triethoxysilane (KH550) to reduce the interfacial thermal resistance between filler and epoxy matrix. It was observed that the resultant epoxy composites provided a higher thermal conductivity of 0.57 W m −1 K −1 than that of neat epoxy (0.17 W m −1 K −1 ).…”

Polydopamine (PDA) was employed to modify micrometric Al2O3 platelets to improve the interfacial compatibility between α‐Al2O3 powder and ultrahigh‐molecular‐weight polyethylene (UHMWPE). The structure of PDA‐coated Al2O3 and UHMWPE composites was investigated via Fourier transform infrared spectroscopy, scanning electron microscopy and X‐ray photoelectron spectroscopy. The thermal stability and mechanical performance of the samples were also evaluated. It is clear that UHMWPE/PDA‐Al2O3 composites exhibit better mechanical properties, higher thermal stability and higher thermal conductivity than UHMWPE/Al2O3 composites, owing to the good dispersion of Al2O3 powder in the UHMWPE matrix and the strong interfacial force between the macromolecules and the inorganic filler caused by the presence of PDA. The tensile strength and the tensile elongation at break of UHMWPE/PDA‐Al2O3 composite with 1 wt% PDA‐Al2O3 are 62.508 MPa and 462%, which are 1.96 and 1.98 times higher than those of pure UHMWPE, respectively. The thermal conductivity of UHMWPE/PDA‐Al2O3 composite increases from 0.38 to 0.52 W m−1 K−1 with an increase in the dosage of PDA‐Al2O3 to 20 wt%. The results show that the prepared PDA‐coated Al2O3 powder can simultaneously enhance the mechanical properties and thermal conductivity of UHMWPE. © 2018 Society of Chemical Industry

The present work describes preparation of modified alumina with biocompatible, water soluble, and treating agents such as citric acid and ascorbic acid. Also, the influence of the modified nanoparticles (NPs) into the blend of poly(vinyl alcohol)@poly(vinyl pyrrolidone) (50/50) matrix was studied. At first, citric acid and ascorbic acid as environmental friendly agents were grafted on the surface of Al2O3 NPs. Then, nanocomposites (NCs) with different amounts of modified Al2O3 NPs were prepared via a simple ultrasonic method. The characterizations of the molecular structure of the NCs specified that chemical and physical interactions happened between inorganic and organic counterparts. The mutual effect of modified NPs into the polymer matrix was investigated on the structural, interfacial interaction, thermal stability, and optical properties. The results from morphological characterization confirmed changes in morphology of poly(vinyl alcohol) and poly(vinyl pyrrolidone) after loading NPs. Uniform dispersion of modified spherical Al2O3 NPs powders into the matrix of 50/50 polymers was detected by field emission scanning electron microscopy and energy‐dispersive X‐ray. Adding M‐NPs into the polymer matrix expressively improved the thermal stability of NCs. Peaks in ultraviolet–visible spectra were shifted to the higher absorption.
