Direct Current Electrical Transport and Magneto Transport Properties of Polyaniline Nanocomposites

Abstract

Polyaniline nanocomposites were prepared by in-situ polymerization with hydrochloric acid (HCl), Copper Chloride (CuCl2) and multiwall Carbon Nanotube (MWCNT). The samples were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM). Direct current electrical conductivity was measured within a temperature range 77≤T≤300K in presence and in absence of a magnetic field up to 1Tesla. The dc transport properties of the samples follow the variable range hopping (VRH) theory. The magnetoconductivity of the samples have been explained by wave function shrinkage model and forward interference model.
