摘要
阐述当设计不同长短的联接基团链时可控制低聚表面活性剂单元分子内离子头基间的距离 ,这使单元分子的几何形状、头基电荷密度和水化程度及烷烃链密度发生变化 ,单元分子的这些变化直接影响低聚表面活性剂分子聚集体的状况 ,从而实现从分子结构水平上调控其分子有序聚集体的形状和表面电荷密度。
Oligomeric surfactants are made up of two identical amphiphilic moieties covalently connected at the level of the headgroups by a spacer group.The distance between the headgroups in oligomeric surfactant can be controlled through designing and synthesizing different lengths in the spacer groups.This implies a change in the shape and in the density of alkyl chains of the surfactant molecule,and also in the charge density of the ionic headgroups and their gydration,which should directly affect their aggregates.The article elaborates the idea of controlling order-aggregate by design and synthesis of oligomeric surfactants with different length in the spacer.
