Abstract
High-performance dielectric polymer materials consisting of ZnS:O nanoparticles (ZSO NPs) with isoelectronic traps and polyvinylidene fluoride (PVDF) were prepared by a solution-casting method. Compared with pure PVDF and PVDF/ZnS composites, the energy density and breakdown strength for polymer nanocomposites with high filler loading are obviously enhanced. By analyzing the physical model we built, we propose that the density and movement of charges are regulated by isoelectronic traps, resulting in increased insulation and a changed mircoelectric field distribution. In addition, this filling strategy also solves the problem of charge accumulation in polymer nanocomposites.
