Dependence of dielectric behavior on the physical property of fillers in the polymer-matrix composites

Dielectric properties of nanosilica/low-density polyethylene composites: The surface chemistry of nanoparticles and deep traps induced by nanoparticles

“…Moreover, at low frequencies the dipoles have sufficient time to align with the field before it changes direction giving rise to high permittivity. At high frequencies the dipoles do not have time to align before the field changes direction and the permittivity is lower [31]. The addition of A200 make permittivity of LDPE increase in the 1-1000 Hz range, but decrease in the 10 000-100 000 Hz range, while the permittivities of R312/LDPE, R805/LDPE and R974/LDPE all reduce to different extents (the insert of Figure 6a), indicating that the charge carriers movement was inhibited in the functionalized nanocomposites [32].…”

Characterization of polypyrrole/azocalix[4]arene salts: Electrical properties and thermal stability

“…This is a characteristic behavior of semiconductors. 26 However, there can also be thermal curing. It affects the chain alignment of the polymer and leads to the increase of the conjugation length, which brings about the increase of conductivity.…”

Study of the Preparation and Dielectric Property of PP/SMA/PVDF Blend Material

“…Therefore, researches focus on the study of polymer blends which combine the performances of the blended polymers. Polymer blends are easy to process and shape, and have great flexibility [4,5]. Meanwhile, the application prospects of polymer blends is extensive, and they can typically be adopted by the modern electronic industry [6,7].…”
