Sensing and antimicrobial activity of polyaniline doped with TiO2 nanocomposite synthesis and characterization

Abstract

Pure PANI and TiO2/PANI nanocomposite composites with widely different TiO2 weight percentages were synthesized by chemical oxidative method. Polymerization of aniline using ammonium per sulfate (APS) in acidic medium at room temperature for the PANI/TiO2 nanocomposite. UV–visible absorption spectroscopy, X-ray diffraction (XRD), Photo luminescence spectroscopy (PL) and Scanning electron microscopy were used to examine the morphological and structural features of these composites (SEM). Dynamic light Scattering (DLS) investigation is performed to find the size of nanocomposite of PANI/TiO2. The multifunctionality of TiO2 nanocomposite doped with PANI was incorporated. The sensing action of diazepam drugs has been widely used. The antimicrobial activity of PANI/TiO2 nanocomposite inhibition efficiency was investigated.
