abstract = {In view of the conductive/insulating multilayer composite structure and micro/nano-size thickness of flexible thermal control film materials, a test was conducted on the charging and discharging characteristics of kapton-based secondary surface mirror film materials using 10~70 KeV electron irradiation. The key parameters such as surface charging potential and electrostatic discharge frequency were obtained. The transport law of irradiated electrons in multilayer thin film materials was studied by Monte Carlo method. The results show that there is no electrostatic discharge when the irradiated electron energy is 10 KeV due to the particularity of the kapton-based secondary surface mirror film structure. With the continuous increase of the electron energy, the surface charging potential amplitude of the film material and the electrostatic discharge frequency show a trend of first increasing and then decreasing. The space charging and discharging effect is most significant when the electron energy is 25 KeV.}
