Tailoring the properties of epoxy/silicone blends for high-voltage capacitor applications

Abstract In recent decades, high dielectric constant ( k ) polymer nanocomposites have proved excellent potential in and energy storage applications. Epoxy/silicon rubber composite materials shown promising properties applications such as high-voltage insulation. Three types of nanomaterials (SiO 2 , TiO @SiO with distinct intrinsic are carefully chosen to build high- epoxy/silicone this study. To raise the value K work tailored polarizing ability or permittivity material by inserting different weight ratios nano-fillers base matrix epoxy silicon blends. With a containing 75% 25% liquid silicone concentration, maximum obtained is = 158 for 5% there an increase strength 398 kV/mm. The results indicate that, among three kinds epoxy/silicone, has most enhancing capabilities proposed nanocomposites, owing largest while maintaining low loss leakage current.
