Effect of electron beam irradiation on polyimide film
E-mail:
The effects of electron beam radiation on polyimide films were investigated through dynamic mechanical analysis (DMA), in which the energy of the electron beam was set to a voltage of 1 MeVand a beam current of 4 mA. The b2 sub-glass relaxation temperature of polyimide decreased with irradiation dose, consisting with formation of free radicals at the ends of the molecular chains. The glass relaxation temperatures are not influenced as a function of increasing electron beam exposure because imide rings prevent structural damage by electron beam irradiation. Furthermore, decomposition temperatures of the irradiated polyimide slightly decrease, from 571.42 to 570.67 ℃ and the residue weight also decreases.
