Studies On Electrical Conductance Of Novel Random Copolymers And Photocrosslinking Efficacy Of Their Blend Nanofibers
Journal Title: International Journal of Scientific Research and Management - Year 2015, Vol 3, Issue 9
Abstract
A series of novel random c opolymers with oxy gen bridges were prepared from4,4’ - oxybisbenzoicacid and 1,6 - hexandiol/arylidenediol with varying diols namely, 1,8 - dihydroxyanthraquinone, 4,4’ - dihydroxydiphenyl and 4,4’ - diamino diphenyl - methane using diphenylchlorophosphate as the condensation agent. Their structural features were investigated by viscosity measurements, FTIR, 1 HNMR and 13 CNMR spectral data and thermal behavior was established by Differential Scanning Calorimetry (DSC) and Hot Sta ge Optical Polarised Microsco py (HOPM). The synthesized polymers/PVC blend nanofibers drawn by electrospinning process were tested for photocrosslinking efficacy using UV irradiation technique. The changes in morphology of the nanofibers by UV irradiation were studied by Scanning Elec tron Microscopy (SEM). The frequency dependent dielectric and conductivity behavio u r of the synthesized polymers were studied at different temperatures using LCR meter. Th e synthesized polymers with such unique properties are expected to be of use in ele ctrochemical devices and sensors.
