| 摘 要： | 在较稀的氨水体系中以十六烷基三甲基溴化铵(CTAB)作为模板剂,正硅酸乙酯(TEOS)作为硅源,制得介孔二氧化硅.通过小角X射线衍射(XRD)方法对介孔结构及其有序性进行表征,载银处理之后运用SEM,TEM对得到的抗菌粉体进行表征.将抗菌粉体添加到PP中,对其抗菌性能进行研究.运用XRD,SEM,TEM对得到的抗菌粉体进行表征.结果表明,在氨水体系下68℃时,TEOS/CTAB为5∶2制备出的二氧化硅呈六方介孔结构.抗菌测试显示,随着载银纳米二氧化硅添加量增加材料的抗菌性能提高.

| Abstract: | In a dilute ammonia water system, mesoporous silica was prepared which cetyhrimethylammonium bromide （ CTAB ） and tetraethoxysilane （ TEOS ） were used as template and silica source respectively. The meso-structure was characterized by X-ray diffractomer （ XRD ）. The morphology and micro-structure were characterized in detail by scanning electronic microscopy（ SEM ）and transmission electronic microscopy （ TEM ）after the process of carrying silver. The antibacterial powder is added to the PP, the antibacterial properties were studied. The results showed that in ammonia system under 68 ℃, TEOS/CTAB for 5 ： 2 prepared silica mesoporous structure with six party. Antibacterial test display with silver nanometer silicon dioxide added the antibacterial properties of the materials were improved. |
