摘　　要：与各种高分子合成的水凝胶相比,半纤维素基水凝胶具有难以比拟的优势,如环境友好性、生物兼容性、无毒及可降解性等。文中从制备方法角度归纳和总结了木质纤维半纤维素基水凝胶材料近年来的研究进展以及潜在的商业应用前景,并指出了半纤维素基水凝胶在研究中存在的问题及发展方向。Recently the preparation of functional biomaterials--hydrogel based on hemicelluloses biomass has obtained a special attention, and the product has exhibited important market prospects and application potential. Compared with synthetic polymer hydrogel, hemicellulo- ses-based hydrogel shows significant advantages, such as environmentally friendly property, bio-compatibility, non-toxicity and biodegrad- ability and so on, which is expected to be used in drug delivery, biosensors, and tissue engineering and other areas. According to the cross- linked type, the methods to prepare hydrogel are divided into physical crosslinking and chemical crosslinking. This paper summarized the research progress of hemicelluloses-based hydrogel materials and the commercial application potential, and pointed out the problems existed and the future development direction in the research of hemicelluloses-based hydrogel.
