An amphiphilic compound of long-chain amide derivative bearing hydroxy groups as the terminal groups possessed an ambidextrous gel property, i.e., it made gels in both organic solvents and in aqueous solutions. Further, sol-gel transition of the hydrogel was able to be controlled reversibly by pH. Small-angle X-ray scattering and FT-IR measurements showed that the main interaction of the aggregate
一种以羟基为端基的长链酰胺衍生物的两亲性化合物,具有兼具凝胶特性,即在有机溶剂和水溶液中均能形成凝胶。此外,水凝胶的溶胶-凝胶转变能够通过 pH 值可逆地控制。小角 X 射线散射和 FT-IR 测量表明,聚集体形成的主要相互作用是酰胺基团之间的氢键,并且聚集体在有机凝胶和水凝胶中均具有层状结构。
