Abstract

In this work we report on the preparation of poly(vinylidene fluoride) (PVDF) films with various mass fractions (wt%) of hydrated rare earth metal salt (NH4)(4)Ce(SO4)(4)center dot 2H(2)O] (CAS) and its electroactive phase (beta- and gamma-phase) formation. It was found that CAS can yield high amount of electroactive phases in PVDF. Compared to the neat PVDF film, a significantly increment of dielectric constant (epsilon similar to 41) and a low loss factor (tan delta similar to 0.8) were observed in the PVDF-CAS composite films. Thus the PVDF-CAS composite films with high electroactive phase and superior dielectric properties may meet the requirements of next generation electronic components. (C) 2017 Elsevier Ltd.
