SYNTHESIS, CHARACTERIZATION AND ANTIBACTERIAL ACTIVITIES OF POLYMER CAPPED TITANIUM DIOXIDE NANOPARTICLES

Abstract

Scientific research has demonstrated a growing interest in the topic of nanotechnology in recent years, leading to the development of many ways for producing nanoparticles, including chemical synthesis approaches. In this study, the synthesis, characterization and antibacterial activities of polymer capped titanium dioxide nanoparticles. Polyvinyl alcohol serves as a polymer capping agent. The synthesized polymer capped titanium dioxide nanoparticles were characterized by X-ray diffraction (XRD), Scanning electron microscopy SEM with EDAX, Atomic force microscopy (AFM), Transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR) analysis. The antibacterial activity of nanoparticles was determined by gram-positive and gram-negative bacteria.
