60-MeV C⁵⁺ion irradiation effects on conducting poly (o-toluidine)–poly vinyl chloride blend films

Abstract

Poly (o-toluidine) was synthesized from a derivative of aniline (o-toluidine) monomer by chemical oxidative polymerization method. After polymerization, the polymer prepared was blended with poly vinyl chloride and irradiated by 60-MeV C 5+ ions at five different fluences of 1 × 10 11 , 3.3 × 10 11 , 1 × 10 12 , 3.3 × 10 12 and 1 × 10 13 ions/cm 2 . The swift heavy ion irradiation effects on crystallinity and DC conductivity were studied. X-ray diffraction study showed variations in crystallinity of the blend films upon irradiation. The crystallinity, DC conductivity and activation energy were found to vary discontinuously with fluence. The DC conductivity and activation energy were obeying Meyer-Neldel rule.

Effects of 60MeV C5+ ion irradiation on PmT–PVC and p-TSA doped PoT–PVC blends

“…These changes in the macro-properties like structural, electrical, optical and thermal properties can be traced to transformations at the micro-level through cross-linking, chain scissoring, bond breaking and cluster formation due to the energy deposited by SHI beam [15][16][17]. Triple bond formation and new crystallite formation is found to have occurred due to C ion irradiation in poly(o-toluidine)-PVC blends [18]. The new bond formation and change in crystallinity leads to a decrease in conductivity and optical band gap in these blends after irradiation [19].…”

Ion Irradiation Effects in some Electro-Active and Engineering Polymers Studies by Conventional and Novel Techniques

“…The conductivity increased with the formation of clusters and craters at higher fluences. 60 MeV C 5+ ion irradiation effects on crystallinity and DC conductivity of poly (o-toluidine)-poly vinyl chloride blend films were investigated by Lakshmi et al [141]. The DC conductivity and activation energy obeyed Meyer-Neldel rule.…”

Studies on structural, optical and cluster size of poly(m-toluidine)–polyvinyl chloride blends

“…The electronic energy loss plays an important role in the modifications of various properties. Triple bond formation and new crystallite formation were found to occur due to C ion irradiation in PoT-PVC blends (18). The new bond formation and change in crystallinity may lead to a decrease in conductivity and optical band gap in these blends after irradiation (19).…”
