Development of PVB-Nano Cellulose based Polymer Electrolyte and Correlation of Optical Behavior with Ionic Conductivity

Abstract

Present work deals with findings on AC conduction and their correlation with FTIR transmittance intensity in a CNF doped polymer nanocomposite electrolyte system, namely [PVB(1-x) + LiSCNx](1-y): CNFy. The structural behavior of electrolytes studied by XRD, SEM and IR spectroscopy and Raman spectroscopy shows improvement in amorphous behavior on dispersal of CNF nanofillers. The effect of CNF on electrical behavior under isothermal conditions, in nanocomposite polymer electrolyte has been investigated by the impedance spectroscopy. The variation of conductivity with temperature and their correlation with FTIR transmittance peak has been investigated. The role of mobility and number of charge carriers in conductivity is also studied.
