title = "Surface flashover performance of epoxy resin microcomposites infulenced by ozone treatment",
abstract = "The influence of ozone surface treatment on surface flashover performance of epoxy resin/Al2O3 microcomposites was investigated. Epoxy resin/Al2O3 microcomposite samples with a diameter of 50 mm and a thickness of 1 mm were prepared and treated by ozone for various periods. Surface potential decay, surface conductivity, secondary electron emission coefficient, and surface flashover voltage in SF6 of untreated and ozone treated samples were measured. Both the decay rate of surface potential and surface conductivity increase with an increase in the energy of electron beam. Meanwhile, surface flashover voltage increase. There was no obvious change in secondary electron emission coefficient by the ozone surface treatment. It was found that the decrease in trap energy and increase in trap density can enhance the charge transport process on the surface of samples. The changes can weaken the distortion of electric field at the triple junction of electrode-dielectric-gas and reduce the electron emission, which will improve the surface flashover performance.",
