| titleOfInvention | Polyetherimide composite medium with multilayer gradient structure and preparation method and application thereof |
| abstract | The invention relates to a polyetherimide composite medium with a multilayer gradient structure, a preparation method and application thereof, and belongs to the technical field of energy storage dielectrics. In order to solve the problem that the energy storage efficiency of an energy storage medium is reduced due to the fact that the energy storage density of the energy storage medium is improved, the invention provides an aluminum oxide and silicon dioxide coated barium titanate/polyetherimide composite material doped with barium calcium zirconate titanate, wherein the composite material is a thin film with the thickness of 10-18 mu m, the matrix of the composite material is polyetherimide, and a filler is aluminum oxide and silicon dioxide coated barium titanate nanofiber doped with barium calcium zirconate titanate; the doping amount of the barium calcium zirconate titanate is 10-50 vol% of the volume of the filler, and the doping amount of the filler is 1-3 vol% of the volume of the composite material. The composite material provided by the invention has excellent energy storage density and energy storage efficiency, and can be applied to a dielectric capacitor to further improve the comprehensive energy storage performance of the dielectric capacitor. |
