Triple-transforming gel prepared byβ-cyclodextrin,diphenylamine and lithium chloride in N,N-dimethylacetamide

<正>This paper describes a triple-transforming gel system(gel-sol-gel') for the first time,which is a thermo-responsive and multicomponent organogel prepared byβ-cyclodextrin(β-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 byβ-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.

Triple-transforming gel prepared by β-cyclodextrin, diphenyl- amine and lithium chloride in N, N-dimethylacetamide

This paper describes a triple-transforming gel system (gel-sol-gel’) for the first time, which is a thermo-responsive and multi-component organogel prepared by β-cyclodextrin (β-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 β-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 (Tgel, the gelation temperature by heating). The two gel states in the triple-transforming gel system have different micro-structures. This gel system was characterized by OM, SEM, IR and Rheology.
