摘要
采用溶胶凝胶法在载银气相二氧化硅表面包覆二氧化钛,制备了一种新型无机抗菌粉体,分别用XRD、TEM对粉体进行观察,抗菌测试表明其抗菌率可达99.9%。
TiO2 is coated on the surface of nano SiO2 carrying Ag using sol-gel route,then a novel nano Ag-type inorganic antibacterial agents has been prepared. The powder has beeh characterized by XRD,TEM. The result of antibacterial performance shows that the powder has a 99.9% bactericidal activity on E .coli .
