摘　　要：本文在超白玻璃配合料中引入AgNO_(3)作为有效抗菌成分,采用高温熔融法制备一种具备高抗菌性的超白玻璃。该玻璃具有良好的可见光透过率、色度值和抗菌性能,其中玻璃在380~780 nm的可见光透过率约为91.5%;随着AgNO_(3)含量的增加,玻璃的明度逐渐降低,黄色相增加,但偏黄程度较低;玻璃对大肠杆菌和金黄色葡萄球菌的抗菌率均超过90%。通过XRD和XPS对玻璃进行了物相分析和掺入Ag元素的价态分析,并通过ICP-OES分析了玻璃样品中Ag^(+)的溶出量。XRD和XPS测试结果表明:该玻璃为非晶态,掺入的Ag元素以Ag^(+)而非Ag单质形式存在;玻璃中的Ag^(+)溶出量随时间增加而增大,但Ag^(+)溶出速率减小,各组玻璃样品在24 h内的Ag^(+)溶出量与抗菌检测结果一致,证实了AgNO_(3)在玻璃中的抗菌性。In this paper,a kind of ultra-clear glass with high antibacterial properties was prepared with high temperature melting method by introducing AgNO_(3)as the effective antibacterial component.The glass has good visible light transmittance,colorimetric value and antibacterial properties,in which the visible light transmittance of the glass at 380~780 nm is about 91.5%.With the increase of AgNO_(3)content,the brightness of glass gradually decreases and the yellow phase increases,but the degree of yellowing is small.The antibacterial rate of glass against Escherichia coli and Staphylococcus aureus is more than 90%.The phase analysis and valence state analysis of Ag were carried out by XRD and XPS,and the dissolution of Ag^(+)in glass samples was analyzed by ICP-OES.XRD and XPS test results show that the glass is amorphous,and the doped Ag element exists in the form of Ag^(+)rather than Ag elemental.In addition,the amount of Ag^(+)dissolved in the glass increases with the increase of time,but the dissolution rate of Ag^(+)decreases.The amount of Ag^(+)dissolved in the glass samples of each group is consistent with the result of antibacterial detection within 24 h,which confirms the antibacterial property of the AgNO_(3)in glass.
