| Abstract: | Polyimide films might be damaged under space high energy particle irradiation. In this paper, the mechanical properties of polyimide film is studied with the 60Co radiation source, the thermo-gravimetric analysis and the XPS analysis. Significant total dose effect and dose rate effects are found in the mechanical properties of the PI film under gamma ray radiation. |

| Keywords: | polyimide film gamma ray mechanical properties total dose effect dose rate effect test study |
