Polypyrrole (PPy) and Montmorillonite (MMT) composites of different weight percentage using FeCl3 as oxidant have been synthesized using in-situ polymerization. The electrical conduction is studied as function of temperature. The electric conductivity increases with an increase in the temperature in each of the composites. Mott’s 1- D, 2-D and 3-D variable range hopping (VRH) models have been plotted. The ln(σ) versus T-1/4 curve has been discussed, wherein the linear relationship provides an evidence for three dimensional variable range hopping electron transport mechanism in all the composites.
