摘要

生物可降解多糖气凝胶是一类以广泛来源于自然界的生物可降解多糖为原料,采用溶胶-凝胶法结合超临界干燥技术或者冷冻干燥技术制得的三维纳米网络结构材料,由于生物可降解多糖具有许多独特的物理、化学和生物特性(如阳离子聚电解质性、生物相容性、生物可降解性、易于化学修饰、安全无毒等),并结合气凝胶材料的高比表面积和高孔隙率等特性,在污水处理、纺织造纸、食品包装和生物医药等领域都有的广泛应用。本文主要介绍了纤维素、壳聚糖、海藻酸钠和魔芋等几种生物可降解多糖气凝胶的研究进展,包括生物可降解多糖气凝胶的常用制备方法、性能及其在不同领域的应用进展。
        Biodegradable polysaccharide aerogel is a material with a three-dimensional nano-network structure,which is prepared by a sol-gel method combined with supercritical drying technology or freeze-drying technology. Because biodegradable polysaccharides have many unique physical, chemical and biological properties combined with the high specific surface area and high porosity of aerogel materials, they are widely used in wastewater treatment, textile paper, food packaging and biomedicine. This paper mainly introduces the preparation, properties and applications in different fields of cellulose, chitosan, sodium alginate and konjac.
