摘要
以双胆固醇取代紫精衍生物形成的有机凝胶纤维为模板,在吡啶催化下合成了内径不同的SiO2纳米管,研究结果表明,体系中TEOS水解生成低聚物的含量对凝胶纤维的聚集会产生影响,并影响最终生成的SiO2纳米管的形貌.
SiO2 nanotubes with different inner diameters were synthesized by using a novel viologen-based organogel as the template. It was found that the content of the silica oligomer produced from the hydrolytes of TEOS had effect on the aggregation of the organogel fibers, which would result in the formation of SiO2 nanotubes with various morphologies.
