Deep charging and discharging effect is one of the key factors threatening the satellites safety in space environment. We develop a new model and simulate the surface potential evolution, internal charge distribution and electrical field distribution in the polymer charged by electron beam of different intensities. The results are compared with experimental results, which show that the polymer′s surface potential increases with electron beam intensity and its resistance, and the time to reach charging equilibrium is determined mainly by the polymer′s resistance.
