Dielectric Constant Enhancement with Low Dielectric Loss Growth in Graphene Oxide/Mica/Polypropylene Composites

Polypropylene has been widely used as dielectric material in organic thin-film capacitors due to their high breakdown strength, low loss and self-healing capability. However, polypropylene’s energy density is relatively low. Increasing the of polypropylene by adding materials with a constant commonly used. Still, it often leads an increase loss, lower strength other shortcomings. In this study, thin 2D platelet mica/graphene oxide composite was made from exfoliated mica substrate attached graphene oxide. The platelets were added make plastic composite. non-conductive flat inorganic additive can without increasing loss. tiny significantly improve properties polypropylene. results show that small amount (less than 1 wt%) oxide, relative more 3.7 causing also enhance.
