离子液体在淀粉研究中的现状及展望

Progress and Prospects of Ionic Liquids in Starch Research

随着全球环保意识的提高,淀粉因其具有广泛的可利用性、良好的生物降解性和可再生性而吸引了众多科研人员的关注.近年来,离子液体以其独特的蒸气压小、不燃性、化学稳定性高、热稳定性好等特点,在淀粉加工及淀粉基材料的制备中被广泛用作“绿色溶剂”.本文综述了淀粉在离子液体或离子液体-其他溶剂混合溶液中的溶解、相转变行为及其分子机制,以及离子液体在新型淀粉材料制备中的应用,并对其未来的研究前景进行了展望.

With the growing awareness of global environmental protection,starch has gained huge interest due to its wide usability,good biodegradability and regeneration.Recently,ionic liquids(ILs)have been used widely as“green solvents”in processing starch and fabricating starch-based materials because of their unique properties such as negligible vapor pressure,nonflammability,as well as high chemical and thermal stability.In this paper,we reviewed the dissolution and phase transition behavior of starch and its molecular mechanism in ILs or the mixture of IL/other solvents,and the applications of ILs in other areas of starch.The prospects of this kind of research were also discussed.
