|Abstract:||FTIR spectroscopy technique has been applied for the analysis of high energy heavy ion irradiated kapton-H polyimide. The kapton-H samples were irradiated with 75 MeV oxygen, 80 MeV nickel and 50 MeV lithium ions at PELLETRON facility, Nuclear Science Centre, New Delhi. A very broad peak in 2500-3500 cm⁻¹ is due to the presence of absorbed water in irradiated samples. The reduction in the intensity of 1702 cm⁻¹ peak in irradiated samples as compared to pristine samples is associated to the demerization of carbonyl groups. The increase in the intensity of this peak with increase in fluence is due to the increase in cross-linked structure causing the reduction in demerization of carbonyl groups. The FTIR spectrum is independent of the nature of ion.|
