| 摘 要： | 以正硅酸乙酯(TEOS)为原料、细菌纤维素为模板制备了高产率、尺寸均匀、超大长径比、具有较稳定宏观形貌的二氧化硅纳米管.借助透射电子显微镜(TEM)、扫描电子显微镜(SEM)、热失重(TGA)等分析方法对样品进行表征,探讨二氧化硅纳米管的形成机理,并考察实验条件对二氧化硅纳米管的产率和形貌等的影响.结果表明:低浓度的硅源、催化剂与较低的焙烧温度,有利于得到分散性良好的SiO2纳米管网络结构. |

| Abstract: | Silica nanotubes with high yields,uniform size,ultra-large aspect ratio and stable macro appearances were syn-thesized from hydrolyzing tetraethylorthosilicate(TEOS)using bacteria cellulose as template.The prepared products were characterized with transmission electron microscopy(TEM)s,canning electron microscopy(SEM)t,hermogravimetic analy-sis(TGA).The formation mechanism of the silica nanotubes and the influence of synthesis conditions on the formation of the silica nanotubes were investigated.The results... |
