A novel nanocomposite made up of polyaniline, polyvinyl alcohol, and silver (PAL/PVA/Ag) was synthesized using the reduction of chemical technique in this study. Aniline was polymerized in situ with ammonium persulfate to create polyaniline (PAL), while Ag+ ions were employed to make an nanoparticle of Ag colloidal solution. The combination of Ag nanoparticles with the PAL/PVA composite resulted in the development of a new nanocomposite. Scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy were used to evaluate the structure and particle size of the novel nanocomposite. The SEM analysis demonstrated that the nanoparticles had a triangular shape, known for its antibacterial properties. Staphylococcus aureus (Staph. aureus) and Escherichia coli were used to evaluate the antibacterial efficacy of the (PAL/PVA/Ag) nanocomposite using the paper disc diffusion technique. The PAL/PVA composite demonstrated no antibacterial properties, but the PAL/PVA/Ag nanocomposites effectively inhibited the growth of both bacteria. The results suggest that the nanocomposite has potential applications in antibacterial therapy. In summary, a new nanocomposite based on PAL/PVA/Ag was effectively synthesized using the chemical reduction method. The nanocomposite had a triangular shape with a particle size range of 15–20 nm, as determined using SEM and FT-IR characterization techniques. The nanocomposite was effective in inhibiting bacterial growth, as demonstrated through its antibacterial action against Staph. aureus and E. coli using the paper disc diffusion method. This nanocomposite may have the potential to be used in the development of new antibacterial agents.
