Electrical Transport Properties of Polyaniline Containing HCl, CuCl[sub 2] and Multiwall Carbon Nanotube

Abstract

Electrical transport properties of hydrochloric acid (HCl) doped polyaniline (PANI) and composite of PANI with Copper Chloride (CuCl2) and multiwall Carbon Nanotube (MWNT) was measured within a temperature range 77⩽T⩽300 K in presence and in absence of a magnetic field up to 1Tesla. The electrical transport properties can be explained by the variable range hopping (VRH) theory. All the samples have shown negative d.c magnetoconductivity at the room temperature but PANI‐HCl sample has shown a transition from positive to negative magnetoconductivity as the temperature is increased.
