摘    要:用凝胶剂高氯酸环(L-11-(N-甲基咪唑)十一烷基天冬酰胺-L-苯丙酰胺)(11mim ClO4)和十六烷基三甲基氯化铵(CTAC)作模板剂,经溶胶-凝胶过程,制备纳米结构二氧化硅.使用冷场发射扫描电镜(FESEM),表征了多种反应条件下样品的形貌和表面结构.结果表明,通过调节CTAC和凝胶剂的质量比,可以得到螺旋介孔二氧化硅纳米纤维,其长度为数百纳米,孔径为3.0nm.

关 键 词:纳米带  纳米管  纳米纤维  介孔  二氧化硅  凝胶剂

Abstract:Helical nanostructured silica was prepared by sol-gel method using a chiral cationic gelator cyclo(L-11-(N-methylimidazolium)undecylasapaginyl-L-phenylalanyl) perchlorate(11mimClO4) and cetyltrimethylammonium chloride(CTAC) as templates.Field emitted scanning electron microscopy(FESEM) was utilized to characterize the shape,size and structure of the products obtained at different reaction conditions.By controlling the mass ratio of gelator to CTAC,mesoporous helical silica nanofibers was obtained.These mesoporous silica nanofibers were hundreds nm in length and 3.0 nm in inner-pore-diameter.
Keywords:nanoribbon  nanotube  nanofiber  mesoporous  silica  gelator
