Enhanced energy density of PVDF-based nanocomposites via a core-shell strategy.

ABSTRACT: In recent years, high energy density polymer capacitors have attracted a lot of scientific interest due to their potential applications in advanced power systems and electronic devices. Here, core-shell structured TiO₂@SrTiO₃@polydamine nanowires (TiO₂@SrTiO₃@PDA NWs) were synthesized via a combination of surface conversion reaction and in-situ polymerization method, and then incorporated into the poly(vinylidene fluoride) (PVDF) matrix. Our results showed that a small amount of TiO₂@SrTiO₃@PDA NWs can simultaneously enhance the breakdown strength and electric displacement of nanocomposite (NC) films, resulting in improved energy storage capability. The 5 wt% TiO₂@SrTiO₃@PDA NWs/PVDF NC demonstrates 1.7
