The research progresses in recent years in the functional materials of hemicelluloses including membrane, hydrogel, absorbent, medical material and catalyst support were reviewed. In addition, the application prospect of hemicelluloses-based functional materials was addressed. Hemicelluloses-based membrane can be used as packing material and food wrapping material, but the problem of lower strength and flexibility should be solved. Hemicelluloses-based hydrogel can be prepared by chemical and physical cross-linking and utilized in medical and environmental fields, but the biocompatibility of chemical cross-linking hydrogel and strength of physical cross-linking hydrogel should be further improved. Furthermore, the hemicelluloses can be applied as absorbent for cleaning waster water and air, as medical material for drug sustained release and antibiosis, and as catalyst support for chemical synthesis. In the future, the hemicelluloses would be expected to be used in the fields of photoelectrical material, tissue engineering material, et al.%综述了近年来半纤维素基功能材料包括半纤维素膜、水凝胶、吸附材料、医用材料和催化剂载体的研究进展,并对其未来应用前景进行了展望.半纤维素膜可以作为包装材料和食品包覆膜,但要解决其强度和韧性低的问题;半纤维素水凝胶可以采用物理和化学交联的方法制备,在医药和环境等领域具有较好的应用前景,但要解决化学交联水凝胶生物相容性较差及物理交联水凝胶强度不够等问题;此外,半纤维素还可以作为吸附材料用于废水和空气净化,作为医用材料用于药物缓释和抗菌,作为催化剂载体用于化学合成,将来还有望在光电材料、组织工程材料等领域得到应用.
