弱相互作用调控表面活性剂自组装(V)——在纳米材料制备方面的应用

Self-assembly of surfactants regulated by weak interactions(V) Application in the preparation of nanomaterials

通过调节表面活性剂之间,表面活性剂与前驱体之间以及表面活性剂与溶剂之间的弱相互作用,可以制备形貌和功能多样的介孔二氧化硅、贵金属纳米材料和超分子材料。除了传统的以表面活性剂形成的聚集体(胶束、囊泡、液晶等)作为模板制备纳米材料外,还可以利用表面活性剂中引入的响应性基团简化制备过程,提高材料的循环使用。采用有机-无机共组装的方法制备超分子材料更是具有广阔的应用前景。

Mesoporous silica, noble metal nanomaterials and supramolecular materials with various morphologies and functions can be prepared by adjusting the weak interactions between surfactants, surfactants and precursors or surfactants and solvents. In addition to the traditional surfactant-forming aggregates(micelles, vesicles, liquid crystals, etc.)as templates for the preparation of nanomaterials, the responsive groups introduced in the molecule can be used to simplify the preparation process and improve the recycling of the materials. The preparation of composite nanomaterials by organic-inorganic co-assembly method has broad application prospects.
