摘要: 新型Cu2O纳米微晶玻璃具有高Cu载量、低成本和易大规模制备等特点,有望成为载银抗菌玻璃较有潜力的替代者。通过采用XRD、Raman光谱、XPS、FESEM和TEM等表征方法重点研究了不同ZnO/K2O比对SiO2-Al2O3-K2O-ZnO-P2O5-B2O3-CuO微晶玻璃显微结构的影响,并分析讨论了其结构-性能关系。结果表明,微晶玻璃中Zn与P元素会富集在Cu元素所在区域的附近,适量的ZnO能使微晶玻璃中析出的Cu2O晶粒尺寸稳定在纳米级别,并能调节微晶玻璃中Cu元素的浸出速率。Cu2O纳米微晶玻璃对大肠杆菌和金黄色葡萄球菌均具有显著的抗菌效果,并能实现对维多利亚蓝B溶液的可见光催化降解,是一种极具发展潜力的新型功能微晶玻璃材料。

Abstract: Novel glass-ceramics containing Cu2O nanocrystallines with features of high Cu loading amount, low cost and easy large scale production is a potential substitute for silver loaded antibacterial glass. In this study, SiO2-Al2O3-K2O-ZnO-P2O5-B2O3-CuO glass-ceramics with different ZnO/K2O were investigated. Their microstructures were characterized by XRD, Raman spectroscopy, XPS, FESEM and TEM. The structure-performance relationship was also discussed. The results indicate that there is an enrichment of Zn and P elements around the region where Cu element locates in the glass-ceramics. An appropriate amount of ZnO makes sure the particles size of Cu2O crystallines precipitated in glass-ceramics be in nano-scale and regulate the leaching rate of Cu element. Glass-ceramics containing Cu2O nanocrystallines exhibit significant antibacterial effects on Escherichia coli and Staphylococcus aureus. They also show photocatalysis activity for degradation of Victoria blue B solution under visible light. It should be a novel functional glass-ceramics material with great potential.

Key words: glass-ceramics, Cu2O nanocrystalline, microstructure, antibacterial property, visible light driven photocatalysis
