Polyaniline (PANI) / Barium zirconate (BaZrO3) composites were prepared by insitu polymerization with 10, 20, 30, 40, 50 wt% of BaZrO3 in polyaniline and characterized by FTIR spectra, X-ray diffraction and scanning electron microscopy. Thermally activated behaviour was seen in D.C. conductivity measurements, where increase in conductivity with increase in temperature was observed. Maximum conductivity was seen in 40 wt% of BaZrO3 in polyaniline. A.C. conductivity studies reveal increase in conductivity of all the composites with increase in frequency. On exposure to LPG gas, variation in resistance of the composites was observed.
