用透射电子显微镜和电子衍射技术研究了合成Imogolite液滴干燥形成的纳米管聚集形态.研究表明,液滴在空气中干燥时,当溶液浓度较高时,Imogolite纳米管形成紧密缠结的网状结构;当溶液浓度较低时,Imogolite纳米管形成取向的管束结构.在乙醇气氛下干燥时,观察到了单根分散的Imogolite纳米管,证实了合成的Imogolite纳米管长度具有多分散性.
Transmission electron microscopy and electron diffraction were used to study the aggregated morphology of nanotubes formed by the synthesis of Imogolite droplets.The results showed that when the droplets were dried in the air, Imogolite nanotubes formed a tightly intertwined network when the solution concentration was high Structure.When the concentration of solution is low, the tube structure of the Imogolite nanotube is oriented.When it is dried under ethanol atmosphere, a single dispersed Imogolite nanotube is observed, which confirms the polydispersity of the synthesized Imogolite nanotube.
