摘要
选用硝酸银为原料,硼氢化钠为还原剂,室温下制备了平均粒径为31 nm的银颗粒并对其抗菌性能进行了检测,结果表明:纳米银对大肠杆菌具有良好的抗菌性能。以石英玻璃基片为载体,带负电荷的氧化石墨烯为模板,采用简单易操作的提拉法,依次提拉氧化石墨烯溶液和银溶胶,制备具有抗菌功能的镀膜玻璃。
Using silver nitrate as raw material and sodium hydrogen as reducing agent, the silver nanoparticles are prepared at room temperature, the average size of silver particles is 31nm and their antibacterial properties are studied. The results show that silver nanoparticles have good antibacterial property against Escherichia coli （E. coli）. Film-coating antibacterial glass is further prepared by simple dip-coating technique. The quartz glass is used as a substrate and the negatively charged graphene oxide and positively charged silver nanoparticles are coated on the glass in sequence. The obtained glass shows good antibacterial property towards E. coli.
