文摘

A thermoreversible self-assemble process from gel (fiber) to sol (vesicle) state in the system alkylamine−ethylene glycol is for the first time monitored by in situ polarized optical microscopy, XRD, ¹H NMR, SEM, SAXRD, FTIR and drop shape analysis. It is found that the solvent molecules are intercalated with alkylamine molecules to form the organogel and vesicle structures. A model based on structural transformation with respect to these alkylamine gelator−solvent assembles is therefore proposed.
