摘要: 以γ-氨丙基三乙氧基硅烷(APTES)为修饰剂,采用嫁接的方法对介孔材料SBA-15进行改性,使其表面接枝上-NH2官能团,采用常规AgNO3溶液浸渍法,制得一种抗菌性能优良,杀菌效果持久的广谱抗菌剂。通过X射线衍射(XRD),红外光谱(FT-IR),电子能谱(EDS),场发射电镜(FE-SEM),热重(TG)等对材料结构和特性进行了表征。XRD和TEM研究表明实验所制备的抗菌剂载体SBA-15具有规则有序的孔道结构。FT-IR和TG数据显示介孔材料表面接枝了氨基。EDS,FE-SEM及TEM研究表明抗菌剂的有效成分银被成功负载到抗菌载体上。

Abstract: The mesoporous SBA-15 was modified with 3-aminopropyl-triethoxysilane via post-synthesis silylation methods. Then the AgNO3 solution was dipped into the modified SBA-15 powder and the antibacterial composites were synthesized. Through XRD,FTIR,EDS,FESEM and TG, these composites were characterized. The experimental results reveal that the amino functional groups were grafted on the mesoporous SBA-15 and the Ag nanoparticles existed in the pore channels of SBA-15.
