Investigation of Antibacterial Application of (PVA/PAA/SrTiO3) New Nanocomposites Films

Abstract

Film of pure polyvinyl alcohol (PVA) and poly-acrylic acid (PAA) blend and PVA/PAA blend mixed with Strontium titanate (SrTiO₃ NPs) were fabricated for antibacterial application against gram positive (S.aureus) and gram negative (E.coli) with high activity, .The nanocomposites films were synthesized with various content of SrTiO₃ NPs are o%,1.8%,3.6%,5.4% and 7.2% .The antibacterial application was determined by using the disc diffusion method .The results indicated that the inhibition zone was increased with the increase in SrTiO₃ NPs content . Finally, the results of antibacterial for PVA/PAA/SrTiO₃ nanocomposites films against organisms (S.aureus and E.coli).Showed high activity for antibacterial.
