摘要
Abstract
The paper adopts a hydrothermal method to synthesize a silver rare earth composite antibacterial agent,using a triblock copolymer PEO PPO PEO(P123)was used as the template and TEOS as the silicon source to prepare SBA-15 mesoporous carrier.Silver and rare earth ions were doped into the SBA-15 mesoporous carrier to investigate the effects of different rare earth elements on the silver loading rate and antibacterial performance of SBA-15.The results indicate that the dual effect of silver ions and rare earth ions could improve the antibacterial activity of the composite material and expand the range of antibacterial spectrum.The silver rare earth composite antibacterial agent with Ag+∶Ce3+=3∶1(molar ratio)had the best performance:the silver content reaches 3.65%;the silver loading rate reaches 76.7%,and the antibacterial rate against Escherichia coli and Staphylococcus aureus was>99%.关键词
