Abstract:
A solvent-non-solvent method invented in our laboratory for preparing non-covalently con-nected micelles (NCCM) was used to intercalate melamine (MA) molecules into stearic acid (SA) bilayers to form the composite nanoparticles with an intercalated nanostructure in which a melamine bilayer is sandwiched between two stearic acid bilayers, NCCM method helps to sufficiently mix the two components in nanospace and meanwhile inhibits the strong tendency of self-crystallization of MA, leading to the intercalation. Although the nanopar-ticles have a regular inner structure, the primary MA/SA nanoparticles have an irregular morphology. Regular nanoparticles were obtained through annealing the suspension of the primary nanoparticles. Through annealing at different temperatures, the MA/SA compos-ite nanowires and vesicles with an intercalated structure were prepared respectively. It is proposed that the morphological change results from the change in the intercalated structure.

摘要:
利用非共价键合胶束的溶剂-非溶剂法制备了具有插层结构的三聚氰胺/硬脂酸复合纳米粒子. 非共价键合胶束法的采用不仅实现了三聚氰胺和硬脂酸两组分分子在纳米尺度上的充分混合,而且有效地抑制了三聚氰胺分子自身的结晶行为. 这为三聚氰胺分子插入到双层硬脂酸分子结构提供了的保证. 研究发现初期制备的三聚氰胺/硬脂酸复合纳米粒子具有不规则的微观形态,通过进一步的退火处理可以得到形态规则的纳米线和囊泡. 由于退火处理在一定程度上改变了插层结构,从而进一步导致粒子的形态的改变.
