MWCNTs-TiO2 core-shell nanoassemblies for fabrication of poly(vinylidene fluoride) based composites with high breakdown strength and discharged energy density

Dielectric polymer composites with high breakdown strength and discharged energy density have potential applications in modern electric power systems. In this study, composites comprising MWCNTs-TiO2 core-shell nanoparticles and poly(vinylidene fluoride) (PVDF) were fabricated by a solution casting method, followed by a melting and quenching process. The obtained composites are γ-phase PVDF dominated and present a dense structure. By the...
