Abstract：
Polycarbonate films were irradiated with 2.1GeV Kr ions at room temperature in vacuum and in atmosphere,respectively. The ion beam induced effects were studied by means of Fourier transform infrared (FTIR) and ultraviolet visible (UV/VIS) spectroscopies in reflective mode. FTIR measurements indicate that the main effects are bond breaking,chain scissions and bond rearrangement. The creation of alkyne is the result of bond breaking and bond rearrangement. UV/VIS measurements indicate that at wavelengths of 380,450 and 500nm,the normalized absorbances follow approximately a linear relationship with the energy deposited density.
