摘要：
The surface flashover voltage of insulator is mainly affected by surface properties of materials. Surface treatment technology has become an important technical means to improve flashover voltage. In this paper, the surface of polytetrafluoroethylene (PTFE) was modified by nitrogen ion implantation. And the properties of the sample were analyzed with X-ray photoelectron spectroscopy (XPS), megger and surface flashover experimental system. The experimental results show that the surface flashover voltage of PTFE modified by ion implantation increase remarkably. After ion implantation, the defluorination and oxidation occur on the surface of the PTFE, the surface resistivity decrease by 2 orders of magnitude. The surface flashover voltage increase with the increase of injection energy.
