The preparation of gamma-poly(vinylidene fluoride)/ZnS nanocomposite for energy storage application

Organic-inorganic nanocomposite film composed of poly(vinylidene fluoride) (PVDF) and zinc sulphide nanoparticles (ZnS-NPs) has been prepared. It is observed that composite film can stabilize the gamma-phase. The PVDF-ZnS composite film exhibits superior dielectric property (epsilon(r) similar to 14 at 1 kHz) than those of pure PVDF. Enhanced saturated polarization (P-sat similar to 0.38 mu C cm(-2)) and remnant polarization values (P-r similar to 0.21 mu C cm(-2)) are obtained in nanocomposite film that indicates to have potential to use as energy storage applications. In addition, ZnS-NPs incorporation also improves dielectric breakdown strength. (C) 2017 Elsevier Ltd. All rights reserved.
