Effect of Temperature and Doping Ratios on Electrical Conductivity of Lignin Resin with Rhodamine B

Abstract

AbstractElectrical conductivity of lignin resin films doped with different ratios of Rhodamine B (0.01, 0.04,0.06,0.08,0.1)%wt, were studied. The composite films prepared using casting method. The resultshowed that the conductivity increased with increasing temperature and doping ratios. The values ofactivation energy decreased with increasing temperature and doping ratios of dyes.
