synthesis and characterization of tio2, ag2o, and graphene oxide nanoparticles with polystyrene as a nonocomposites and some of their applications

In this study, metal oxides nanoparticles tio2 and ag2o nps were synthesized by green method using sider leaves extract. the nano-composites were prepared from condensation reaction of polystyrene (ps), tio2, ag2o, and (go) by a simple mixing method. these structures as (ps/go/ag2o) and (ps/tio2/ag2o) were characterized by x-rays diffraction, fe-sem, tem, and thermal analysis. the measurements proved that all the components, of polystyrene (ps), graphene oxide (go), tio2, and ag2o were present and that the size of the nanoparticles within nano-scale. nano-composites were tested in biological activity applications as anti-bacterial and anti-fungal, the results proved that (ps/go/ag2o) nano-composites gave a higher inhibition value than (ps/tio2/ag2o) nano-composites with bacteria, but it gave the result when applied to fungi.
