Polymer nanocomposites with high energy density and low dielectric loss are highly desirable in electronic electric industry. Achieving the ability to tailor interface between polymer nanoparticle is key issue realize properties nanocomposites. However, understanding of role on still very poor. In this work, we report a novel strategy improve constant nanoparticles (i.e., BaTiO3) ferroelectric [i.e., poly(vinylidene fluoride-co-hexafluoro propylene)]. Core–shell structured BaTiO3 either different shell thickness or molecular structure were prepared by grafting two types fluoroalkyl acrylate monomers via surface-initiated reversible addition–fragmentation chain transfer (RAFT) polymerization. The storage capability corresponding investigated broadband spectroscopy displacement-electric field loop measurement, respectively. results show that successfully realized Moreover, densities P(VDF-HFP)-based could be tailored adjusting fluoro-polymer shell. approach described applicable wide range matrix, thereby providing new route for preparing polymer-based used
