AbstractPolymeric nanocomposite materials that are highly thermally conductive are important to a variety of applications, with examples ranging from flexible radiators in space to high-performance aircrafts and vehicles and to cutting-edge electronics. Among widely used nanoscale fillers in the development of these materials are carbon nanotubes and graphene sheets. As concluded in previous reviews, the performance of carbon nanotubes for imparting high thermal conductivity into polymeric matrices was generally poor. Here recent results associated with the effort on significant performance improvements are reviewed as an update. By contrast, graphene sheets have emerged as effective nanoscale fillers for polymeric nanocomposites of excellent thermal transport performance, reaching levels that are competitive to those achieved by metals. The significant recent results on thermally conductive polymeric nanocomposites with graphene sheets are highlighted, and their potential applications and issues on their further performance improvements are discussed.

The synthesis of polymer-grafted nanoparticles (PGNPs) or hairy nanoparticles (HNPs) by tethering of polymer chains to the surface of nanoparticles is an important technique to obtain nanostructured hybrid materials that have been widely used in the formulation of advanced polymer nanocomposites. Ceramic-based polymer nanocomposites integrate key attributes of polymer and ceramic nanomaterial to improve the dielectric properties such as breakdown strength, energy density and dielectric loss. This review describes the ”grafting from” and ”grafting to” approaches commonly adopted to graft polymer chains on NPs pertaining to nano-dielectrics. The article also covers various surface initiated controlled radical polymerization techniques, along with templated approaches for grafting of polymer chains onto SiO2, TiO2, BaTiO3, and Al2O3 nanomaterials. As a look towards applications, an outlook on high-performance polymer nanocomposite capacitors for the design of high energy density pulsed power thin-film capacitors is also presented.

Weak absorption remains a vital factor that limits the application of two-dimensional (2D) materials due to the atomic thickness of those materials. In this work, a direct chemical vapor deposition (CVD) process was applied to achieve 2D MoS2 encapsulation onto the silicon nanopillar array substrate (NPAS). Single-layer 2D MoS2 monocrystal sheets were obtained, and the percentage of the encapsulated surface of NPAS was up to 80%. The reflection and transmittance of incident light of our 2D MoS2-encapsulated silicon substrate within visible to shortwave infrared were significantly reduced compared with the counterpart planar silicon substrate, leading to effective light trapping in NPAS. The proposed method provides a method of conformal deposition upon NPAS that combines the advantages of both 2D MoS2 and its substrate. Furthermore, the method is feasible and low-cost, providing a promising process for high-performance optoelectronic device development.

Based on the results of research works reflected in the scientific literature, the main examples, methods and approaches to the development of polymer inorganic nanocomposite materials for target membranes are considered. The focus is on membranes for critical technologies with improved mechanical, thermal properties that have the necessary capabilities to solve the problems of a selective pervaporation. For the purpose of directional changes in the parameters of membranes, effects on their properties of the type, amount and conditions of nanoparticle incorporation into the polymer matrix were analyzed. An influence of nanoparticles on the structural and morphological characteristics of the nanocomposite film is considered, as well as possibilities of forming transport channels for separated liquids are analyzed. Particular attention is paid to a correlation of nanocomposite structure-transport properties of membranes, whose separation characteristics are usually considered within the framework of the diffusion-sorption mechanism.

Corrosion is a serious problem for implementing metallic components and devices in industrial zones. Considerable effort has been made to develop corrosion prevention strategies. Initially, paints, pigments, and organic coatings have been applied to prevent metal corrosion. Consequently, conjugated polymers, epoxy resin, phenolics, acrylic polymers, and many thermoplastics as well as thermoset resins have been used to inhibit corrosion. Lately, nanofillers such as fullerene, nanodiamond, graphene, graphene oxide, carbon nanotube, carbon black, nanoclay, and inorganic nanoparticle have been introduced in polymeric matrices to harness valuable corrosion protection properties of the nanocomposite. Corrosion protection performance of a nanocomposite depends on nanofiller dispersion, physical and covalent interaction between matrix/nanofiller and nanofiller adhesion to the substrate. Moreover, a high performance anti-corrosion nanocomposite must have good barrier properties, and high scratch, impact, abrasion, and chemical resistance. Thus, polymeric nanocomposites have been found to prevent corrosion in aerospace and aircraft structural parts, electronic components, bipolar plates in fuel cells, and biomedical devices and systems. However, numerous challenges need to be addressed in this field to attain superior corrosion resistant nanocomposites. Future research on polymer nanocomposites has the potential to resolve the current challenges of metal corrosion through entire replacement of metal-based materials with advanced nanomaterials.
