文摘

This paper describes a novel double phase transforming organogel (gel鈥搒ol鈥揼el鈥? composed of nontoxic 尾-cyclodextrin, potassium carbonate, and 1,2-propylene glycol. The gel鈥搒ol鈥揼el鈥?transforming processes are followed by a reversible gel鈥搒ol transforming process and an irreversible sol鈥揼el鈥?transforming process based on heating. The gel鈥搒ol鈥揼el鈥?transformation is accompanied by microstructure changes from nanospheres to nanorods. K₂CO₃ plays a key role in associating supramolecular architectures of 尾-cyclodextrin into a three-dimensional network. This work may bring further applications in the areas of smart materials, drug delivery systems, and biomaterials.
