| 摘 要： | 甲壳素是重要的可再生生物质资源,但其难溶性限制了它的应用。综述了甲壳素溶剂的重要研究进展,包括钙溶剂和离子液体等绿色溶剂以及浓碱-冻融循环处理溶解甲壳素的方法。钙溶剂和离子液体能在温和的条件下溶解甲壳素,对甲壳素结构损伤较小,并且使用方便、无毒、对生态和环境友好,可用来制备能广泛用于生物医学或组织工程领域的水凝胶膜和支架材料,对它们的深入研究有望推进甲壳素科学和绿色化学的发展;而浓碱-冻融循环处理因其快捷、方便、廉价、易控,有望成为一种有效的甲壳素前处理手段。 |
| 关 键 词： | 甲壳素 生物质 绿色溶剂 均相溶液 钙溶剂 离子液体 浓碱-冻融循环 |

| Abstract: | Chitin is an ideal linear heteropolymer which is regarded as a high value-added,renewable biomass resource.However,it is insoluble in water,diluted acid,alkaline solution and common organic solvents.This strongly restricts its many applications.The important developments of the solvent system for chitin were summarized in this article,including calcium solvent,ionic liquid and a novel method as alkali-freezing-thawing cyclic(FTC) treatment for dissolving chitin.Chitin can easily be dissolved in calcium solv... |
| Keywords: | chitin biomass green solvent homogeneous solution calcium solvent ionic liquid alkali-freezing-thawing cycle |
