The present paper reveals the synthesis of polyaniline, polyaniline nanoparticles and polyaniline composite. Improvement of polyaniline properties can be achieved either by forming composites and nanocomposites of aniline, or blends with commercially available polymers or inorganic materials which offer better mechanical and optical properties, stability and process ability. Thus nanostructured (nanoparticles/-rods/-wires) conducting polyaniline offer great research interests. The synthesis of Polyaniline nanoparticles have been studied by sonochemical techniques. The synthesized nanoparticles were characterized by TEM images. The PANI/PVA/Ag nanocomposites were synthesized by chemical oxidation polymerization of aniline monomer in the presence of PVA and Ag nanoparticle colloidal solution. The antibacterial activity of the obtained nanocomposite was evaluated against Gram positive bacteria Staphylococcus aureus (S. aureus) and gram negative bacteria Escherichia coli (E. Coli) using paper disc diffusion method. The antibacterial study showed that the PANI/PVA composite did not have a very good antibacterial activity but PANI/PVA/Ag composites were found to be effective against two bacteria.
