Effect of $$gamma$$-irradiation on latent tracks of polyethylene terephthalate (PET) film

Hiroki, Akihiro; Asano, Masaharu; Yamaki, Tetsuya; Yoshida, Masaru

The pre-treatment effect of $$gamma$$-irradiation on latent tracks of polyethylene terephthalate (PET) films bombarded with swift heavy ions was investigated by electric conductometry and scanning electron microscopy (SEM) observation. The Xe-ion bombarded PET films were etched for 6 hours in 0.2 M NaOH aqueous solution at 70$$^{circ}$$C to prepare track-etched membranes. As $$gamma$$-irradiation doses increased in the range of 0-160 kGy, the pore diameter obtained by SEM observation decreased while that obtained by conductometry became large. This inconsistent result between the two methods was due to an increase in the crosslinked region in the latent tracks caused by $$gamma$$-irradiation.
