| Description |
Application of polymer-salt composite in multifaceted modes viz. as electrolyte, dielectric etc. demands its stability in extreme environmental conditions of high energy radiation zones. The present study reports the behavior of poly (ethylene oxide) PEO] - (polyvinylidene fluoride) PVDF]-KBr composite perturbed by swift heavy ion (SHI) irradiation in the range of tens of MeV. Least conducting PEO-PVDF-KBr is subjected to O7+ ion beam (80MeV) with fluence of 5x10(10) and 5x10(11) ions.cm(-2) respectively. FTIR studies confirm the structural stability of such composite in the mentioned SHI energy regime. SHI perturbation is found to reduce the ionic conductivity of PEO-PVDF composite; however, it could be effectively used as dielectric material for the long term as established from the long-term endurance study (18,500h). Mechanical property evaluation reveals significant increment in nanohardness and Young's modulus of the films perturbed by ion beam. These observations from FTIR, impedance, and XRD are correlated with the morphology of these films.
