Poly(styrene-co-divinyl benzene) was irradiated under gamma-rays at various doses up to 25.6 kGy. The samples were analyzed by Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) before and after the irradiation, and the flashover voltage of materials under different irradiation dose was measured. Results showed that the surface of material was oxidized after irradiation and the oxygen content was the highest (12.29%) when the irradiation dose was 19.2 kGy. In addition, flashover voltages decreased for irradiated samples as compared with the non-irradiated one (R0), and their flashover voltages values were inversely proportional to the oxygen content.
