Abstract—

The structure and dielectric properties of new hybrid polymer nanocomposites based on polyvinylidene fluoride (PVDF) and CdS and ZnS nanoparticles (NPs) have been studied. It was established that ZnS and CdS NPs, when added at low concentrations, define the structure of the host polymer matrix, and new polar groups and stable charge traps arise, which, in turn, leads to an increase in the dielectric permittivity and polarizing ability of the nanocomposites based on PVDF + CdS/ZnS NPs. As the NP concentration is increased, the NPs start to behave like a separate dispersion phase, and the conductivity of nanocomposites grows as the content of this phase increases, which results in the nanocomposite’s polarizing ability gradually diminishing.

基于聚偏二氟乙烯和CdS / ZnS纳米粒子的新型杂化聚合物纳米复合材料：结构和介电性能

摘要—

研究了基于聚偏二氟乙烯（PVDF），CdS和ZnS纳米颗粒（NPs）的新型杂化聚合物纳米复合材料的结构和介电性能。已经确定，当以低浓度添加ZnS和CdS NP时，就可以定义主体聚合物基质的结构，并且会出现新的极性基团和稳定的电荷陷阱，从而导致介电常数和极化能力的提高。 PVDF + CdS / ZnS NPs的纳米复合材料的制备。随着NP浓度的增加，NP开始表现得像一个单独的分散相，随着该相含量的增加，纳米复合材料的电导率也随之增长，这导致纳米复合材料的极化能力逐渐降低。
