摘要: Abstract To describe the damage process of polymer in energetic heavy ion tracks by thermal spike model, polycarbonate (PC, Makrofol KG) foil stacks were irradiated with various swift ions (1.158 GeV Fe56, 1.755 Xe136 and 2.636 U238) a very wide electronic stopping power range (from 1.9 to 17.1 keV/nm) fluence from 1 × 1010 3 × 1012 ions/cm2. The amorphous processes chemical degradation PC studied X-ray diffraction Fourier transform infrared spectroscopy measurements. By applying saturated track mean radii alkyne formation obtained for Fe, Xe U irradiation, respectively. results validated model. analysis films shows that predictions model Szenes are basically quantitative agreement experimental results.
