Pr eparation of polystyrene-Zn Onanoco mposite via solution mixingan d investigation its antibacterial prop erty

In the last few decades, muc h attention has been paid topreparation of organic/nano meter-sized inorganic particlesnanocomposites due to their attractive mechanical,thermal, o ptical, electrical, magnet icproperties, and poten tial application in the areas of plastics andrubber reinforcement, co atings, electronics, ca talysis, an ddiagnostics.Nano-ZnO, as one of the multifunctional in organicnan oparticles, is not only an importan t semiconductormateri al but also serves widel y as catalyst for chemic alreactions, photocataly sts, photoe lectricconversion, antibacterialand bactericide, UV-shielding material, andphotoluminescent materials.Metal oxides such as Mg O, CaO, and ZnO poss ess antibacte rial activity against som e bacteria strains such as S. aureusandE. coli. ZnO nan oparticle exhibited sign ificant antifungal properties against Staphylococcus aureus and P seudomonas aeruginosa. The use of inorganic antibacterial age nts in nonfood applic ations has attracted interest for the control of microbes.This study investiga te the antim icrobial activity of different amou nts of zinc oxides against Aspergillus sp.[۱-۵].
