Excellent Anti-bacterial Activity of Poly(o-toluidine)-DBSA/ ZnO Nanocomposite

Abstract

This work presents a study of the biological application (antibacterial activity) of ZnO/poly(o-toluidine) (POT) doped with organic acids dodecylbenzene sulfonate acid (DBSA) nanocomposites synthesized by in-situ polymerization of (o-toluidine) monomer in presence of 5% ZnO. The FTIR spectroscopy confirms the existence of an interaction between POT-DBSA matrix and ZnO particles. Scanning electron microscopy reveals the nanostructure nature of the obtained composite. The antibacterial activity of POT-DBSA/ZnO nanocomposite and POT-DBSA studied by agar well diffusion method, was found to increase with increasing concentration meanwhile POT/DBSA/ZnO exhibits better antibacterial activity compared to POT/DBSA and POT separately.

Keywords: Poly(O-toluidine); Organic acid; ZnO; nanocomposite; antibacterial activity.
