Abstract
In situ polymerization of aniline was carried out in the presence of molybdenum trioxide to synthesize polyaniline/molybdenum trioxide composites (PANI/MoO3) by chemical oxidation method. The composites have been synthesized with various compositions (10, 20, 30, 40 and 50 wt%) of MoO3 in PANI. The surface morphology of these composites was studied with scanning electron micrograph (SEM). The PANI/MoO3 composites were also characterized by X-ray diffractometry (XRD) and infrared spectroscopy (FTIR). The ac conductivity behaviour has been investigated in the frequency range 102–106 Hz. The dc conductivity has been studied in the temperature range from 40 °C to 200 °C and supports the one-dimensional variable range hopping (1D-VRH) model proposed by Mott. The presence of MoO3 in the matrix has a greater influence on the observed conductivity values than that of PANI. The results obtained for these composites are of scientific and technological interest.
