 Abstract:In order to improve the corona resistance properties of polyesterimide resin nanoAl2O3 sol was prepared by microemulsionhydrothermal method and dispersed into polyesterimide resin solution by mechanical blending then nanoAl2O3 hybrid polyesterimide composite material was prepared The results show that the nanoparticles are dispersed in the polyesterimide matrix With the increase of doping amount the corona resistance of the composites increases but the dielectric strength decreases When the doping amount was 12% its coronaresistant life is 5 times more than pure polyesterimide resin and the dielectric strength is 1752kV/mmWith the increase of the doping amount the dielectric loss of the material is little affected but the dielectric coefficient increases slightly The nanoAl2O3 particles in matrix have little effect on the heat resistance of the material
