Effect of swift heavy ion irradiation on ethylene-chlorotrifluoroethylene copolymer

摘要

The swift heavy irradiation induced changes taking place in ethylene-chlorotrifluoroethylene (E-CTFE) copolymer films were investigated in correlation with the applied doses. Samples were irradiated in vacuum at room temperature by lithium (50 MeV), carbon (85 MeV), nickel (120 MeV) and silver (120 MeV) ions with the fluence in the range of 1 x 10~(11)-3 x 10~(12) ions cm~(-2). Structural and thermal properties of the irradiated as well as pristine E-CTFE films were studied using FTIR, UV-visible, TGA, DSC and XRD techniques. Swift heavy ion irradiation was found to induce changes in E-CTFE depending upon the applied doses.
