SYNTHESIS, CHARACTERIZATION AND DC CONDUCTIVITY OF POLYANILINE/TITANIUM DIOXIDE COMPOSITES

Polyaniline composites using metal oxides have wide variety of applications because of its enhanced properties to that of pure polyaniline. Here, titanium dioxide is employed as the metal oxide to synthesize Polyaniline composite (PANI-TiO2) through in-situ chemical oxidative polymerization. The obtained PANI-TiO2 is characterised for X-Ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM). DC conductivity was studied in the temperature range from 30–180 0C. It is observed that conductivity remains constant up to 100 0C and then increases exponentially.
