摘　　要：以玻璃为基片,采用溶胶-凝胶法,制备了掺杂锌的自洁玻璃表面膜,利用紫外吸收光谱及接触角测定仪等测试手段,研究了锌的不同掺杂量对自洁玻璃表面膜的光催化性能及对不同的菌群的抑菌作用的影响,发现掺杂锌能提高光催化性能和抑菌性能且二者之间有相似的变化趋势。另外还测定了样品具有较好的亲水性能以及掺杂锌后禁带宽度变窄。This paper presents preparation of TiO2 films doped zinc acetate on glass substrate by sol-gel method for making self-cleaning glass. The ultraviolet spectrum,photocatalytic efficiency,contact angle and inhibition ratio of Straphytococcus aureus and Escherichia coli for self-cleaning glass were determined. It indicates that TiO2 films doped zinc acetate could elevate the inhibition ratio and photocatalytic efficiency. The trend of inhibition ratio consistents with that of photocatalytic efficiency,the results also show the film has narrower energy gap and good photoinduced hy-drophilicity which is needed by self-cleaning glass.
