Abstract

A new nancomposite based on polyvinyl alcohol/polyaniline/Ag (PVA/PA/Ag) has been synthesized. An eco-friendly chemical reduction method was used to produce Ag nanoparticle solution from Ag+ ions. The polymerization of aniline occurred for the preparation of poly aniline (PA) in the presence of ammonium persulfate. With exposure to Ag nanoparticles on the PVA/PA composite, a new nanocomposite was obtained. The morphology of the new nanocomposite was studied by scanning electron microscopy (SEM), fourier transorm infrared (FT-IR) analysis, and x-ray diffraction (XRD). According to XRD analysis, the size of nanoparticles was found to be in the range of 15-20 nm. SEM images showed the shape of nanoparticles as triangle which is a benign shape for antibacterial analysis. The bacterial activity of the obtained nanocomposite was also evaluated against Gram negative Escerichia coli (E.coli) and Gram positive bacteria staphylococcus aureus (staph. Aureus) by the disc diffusion method. The antibacterial study showed that the PVA/PA/Ag composite had good antibacterial activity and PVA/PA/Ag nanocomposites were found to be effective against two bacteria.
