Synthesis and characterization of natural polymer/inorganic antibacterial nanocomposites

In order to increase antibacterial abilities and avoid the aggregation of nanoparticle, Ag-ZnO nanocomposites were studied in the network structure which contains bonds, and these bonds are formed by hydrolysis reaction between Ti(TBOU)₄(TBOT) and the water that in Persimmon tannin solution. The size and morphology of Ag-ZnO nanocomposites were investigated by scanning electron microscopy (SEM) and field emission scanning electron microscopy(FE-SEM). The antibacterial properties of nanocomposites were examined by minimal bactericidal concentration(MBC). Results showed that this kind of antibacterial nanocomposites composites(ANPs) have excellent antibacterial abilities and without aggregation.
