| 英文摘要 | Polycarbonate (Makrofol kg) film stacks were irradiated by 15.14 MeV/amu Xe-136 and 11.4 MeV/amu U-238 in the electronic stopping power range (7.6-17.1 keV/nm) and the fluence range from 9 x 10(9) to 1 x 10(12) ions/cm(2). The chemical degradation of the function group was investigated by Fourier-transform infrared (FTIR) spectroscopy and the crystallinity was analyzed by X-ray diffraction (XRD) measurement. FTIR results reveal that the material suffers serious degradation after irradiation. The alkyne group was found after irradiation and their formation cross-sections were evaluated. XRD measurements show the decrease of the main XRD peak intensity, confirming that the material to be amorphised under irradiation. The ion induced amorphisation cross-section was extracted from the fitting of the experimental data for different electronic energy loss irradiations. The degradation cross-section, the formation cross-section and the amorphisation cross-section versus electronic energy loss were discussed. (C) 2002 Elsevier B.V. All rights reserved. |
