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.
