Microwave-assisted synthesis of Ag/ZnO hybrid filler, preparation, and characterization of antibacterial poly(vinyl chloride) composites made from the same

Abstract

Hybrid silver/zinc oxide (Ag/ZnO) nanostructured microparticles were obtained via the fast and simple microwave-assisted synthesis. The phase structure of filler particles was revealed by X-ray diffraction analysis. Composites with medical-grade poly(vinyl chloride) were prepared with filler concentration from 1 to 5 wt%. The scanning electron microscopy was used for morphology characterization and elemental analysis of both filler and composites. The mechanical properties of composites and the electrical resistivity were found suitable for medical device application. The excellent surface antibacterial performance of the prepared composite tested according to ISO 22196:2007 against Escherichia coli and Staphylococcus aureus showed the reliability of the material in the medical application field. © 2013 Society of Plastics Engineers.
