Abstract
The radiation effects on semicrystalline poly(vinylidene fluoride–chlorotrifluoroethylene) copolymer [poly(VDF–CTFE)] induced by proton beam irradiation were investigated. The poly(VDF–CTFE) films were exposed to 4 MeV protons at different fluence in the range of 2.7 × 1013 to 65.0 × 1013 protons/cm2. Changes in the chemical structural and thermal properties of pristine films as well as irradiated samples were studied using Fourier Transform Infrared (FTIR) and thermal analytical techniques, namely Thermogravimetric Analysis and Differential Scanning Calorimetry (DSC), respectively. FTIR spectroscopic data revealed two new bands at 1650 and 1747 cm−1 for irradiated samples whose intensities gradually increased with increasing ion fluence from 2.7 × 1013 to 27.0 × 1013 protons/cm2 due to the formation of carbon–carbon double bonds. The thermal stability was found to decrease after proton irradiation due to chain-scission. DSC data revealed that the proton irradiation was found to change in heat of fusion and crystallinity depending upon the applied dose.
