| 摘 要： | 采用溶胶-凝胶法,合成了铜银改性的六方介孔二氢化硅(hexagonal mesoporous silica,HMS)无机抗菌材料,通过X射线衍射、顺磁共振、紫 外漫反射、Fourier红外、热重-差热分析、环境扫描电镜、电子能谱及N2的吸附-脱附技术对材料结构进行了表征,并以大肠杆菌、金黄色葡萄球菌、枯草杆菌及芽孢杆菌为实验对象考察了材料的抗菌性能.结果表明:铜、银已引入HMS载体的骨架,材料的介孔结构、孔径、粒子形貌等也发生了明显变化,脱模的热化学过程大大缩短,对紫外-可见光吸收明显增强;抗菌实验显示材料抗菌惟能良好.对枯草杆菌及芽孢杆菌的抗菌效果最佳,铜银原位改性HMS的用量为1.00g/L,12h后即可将两者彻底杀灭. |
