Reduced polyaniline decorated reduced graphene oxide/polyimide nanocomposite films with enhanced dielectric properties and thermostability

Interface design for high energy density polymer nanocomposites

“…To date, core-shell structured nanoparticles have been explored in depth for surface modification and multi-functional applications. [64][65][66][67] In polymer based nanocomposites, the ability to enhance dispersion of nanofillers and tailor the interfacial properties remain important technical challenges to be addressed [68][69][70] and the surface modification of fillers with a variety of organic modifiers is an effective approach to overcome these issues. 71,72 Organic modifiers can be physically adsorbed onto the filler surface through electrostatic interactions or by hydrogen bonding.…”

A reduced graphene oxide–borate compound-loaded melamine sponge/silicone rubber composite with ultra-high dielectric constant

“…This ultrahigh dielectric constant in rGO-based polymer composites has been seldom reported in the current literature. [37][38][39][40][41][42][43][44][45][46][47][48][49] Table 1 presents a comparison between the dielectric properties of different composites with graphene as the conductive ller and different polymers as the matrix reported in the literature in recent years; as can be seen from the table, the dielectric constants of most of the reported composites are less than 2000, a few of them are between 2000 and 10 000, and scarcely any of them are more than 10 000. A high dielectric constant generally corresponds to a high dielectric loss, and a low dielectric loss corresponds to a low dielectric constant.…”

Significantly enhanced dielectric constant and energy storage properties in polyimide/reduced BaTiO3composite films with excellent thermal stability

“…18 and 19)) into a polymer matrix to form composites. [20][21][22][23] This approach has been extensively studied for various polymer matrices including poly(vinylidene uoride) (PVDF), polymethylmethacrylate (PMMA), 24 polyimides 25 and epoxy resins. 26 The dielectric constant of ferroelectric/polymer composite system can be improved by a few times compared to the pure polymer when a high content of ferroelectric particles is incorporated (>50 vol%).…”
