摘要:This paper describes a triple-transforming gel system (gel-sol-gel') for the first time, which is a thermo-responsive and multicomponent organogel prepared by beta-cyclodextrin (beta-CD), diphenylamine (DPA) and lithium chloride (LiCl) in N,N-dimethylacetamide (DMAC) in a suitable proportion based on the supramolecular interactions. In the triple-transforming gel system, a gel (gel A) could be formed by beta-CD, DPA and LiCl in DMAC at room temperature based on stirring, then the gel could transform into a clear solution based on heating, and then the other gel (gel B) can be formed at a relatively high temperature (T(gel), the gelation temperature by heating). The two gel states in the triple-transforming gel system have different microstructures. This gel system was characterized by OM, SEM, IR and rheology. (C) 2010 Ai You Hao.
