摘要：

Present work reports about electrical properties of polyaniline (PANI) grafted with electron beam crosslinked chitosan. Measurement of temperature dependent dc & ac conductivity shows a significant improvement in the ac and dc conductivity after doping with 1 M HCl for different time intervals. The dc conductivity results were analyzed using Mott's variable range hopping mechanism. The ac conductivity of grafted polymer obeys power law and behavior of frequency exponent's' has been interpreted by the correlated barrier hopping (CBH) model. The variation of dielectric constant with temperature and frequency is consistent with the Debye type dispersion. (C) 2019 Elsevier Ltd. All rights reserved.
