One-pot synthesis of PANI–TiO2 (anatase) hybrid of low electrical resistance using TiCl4 as precursor

A simple and facile one-pot method for the synthesis of polyaniline (PANI)–TiO2 (anatase) hybrid from TiCl4 as precursor for Titania was experimented. The presence of acetic acid gave anatase form of TiO2 instead of rutile form with HCl as reported in literature. The synthesized hybrid maintained the same amount of TiO2 as in feed ratio. The presence of chemical bonding between PANI and TiO2 was confirmed by FT-IR analysis. Electrochemical impedance spectroscopy studies reveal that hybrid has comparable conductivity with pristine PANI doped with camphor sulphonic acid (CSA).
