Dielectric behaviour of plasma hydrogenated TiO₂/cyanoethylated cellulose nanocomposites

Abstract

The interface between the polymer and nanoparticle has a vital role in determining the overall dielectric properties of a dielectric polymer nanocomposite. In this study, a novel dielectric nanocomposite containing...

Segmental interactions, interfacial polarization, and gigantic dielectric permittivity in ethylene vinyl acetate copolymer‐carbon nanotube composites

“…18 In cyanoethylated cellulose-TiO 2 nanocomposites, the permittivities reached ε r $ 131, which was significantly higher than that of either component alone. 17 This highlights the critical role of the polymer-nanoparticle interface in determining the overall dielectric properties. In conductive polymer composites, polarization depends on electron transport between neighboring conductive fillers, known as domain-type polarization.…”

“…[1][2][3][4][5][6][7][8] Dielectric permittivity is an important property of EPCs that can be used in several advanced applications, such as embedded electronics for energy storage, electromagnetic interference shielding, pulse-powered high-field electronics, and actuators. [9][10][11][12][13][14][15][16][17] Notably, the dielectric properties of certain EPCs have been reported to be markedly better than those of the parent polymer matrix, particularly in the region near the percolation threshold of the conducting filler. 18 For example, Inui et al 14 demonstrated the development of a miniaturized flexible antenna based on an EPC and established that doping with conductive silver nanoparticles increased the value more effectively than doping with BaTiO 3 nanoparticles.…”
