摘　　要：半纤维素是自然界中含量丰富的一类天然杂多糖,具有可再生、生物相容性好、可生物降解等特点,在水凝胶材料的制备领域逐渐受到关注。本文对近年来利用半纤维素制备水凝胶的化学和物理方法进行了概述,重点介绍了化学交联法中的自由基聚合成胶,在物理交联法中,对通过氢键、结晶、冻融等作用成胶进行了总结。此外,对半纤维素与无机纳米粒子混合制备有机/无机复合凝胶的研究进行了说明。最后,对半纤维素基水凝胶材料的应用前景进行了展望。As a class of natural heteropolysaccharides, hemicelluloses are abundant in nature. Due to their reproducible property, favorable biocompatibility and biodegradability, they have gradually been attracted considerable attentions on preparation of hydrogels. This paper reviews both chemical and physical methods on the preparation of hemicellulose - based hydrogels recently. Free radical polymerization are mainly stressed among chemical crosslinking, while physical gelation through interactions including hydrogen bonds, crystallization and freeze -thawing are summarized. Furthermore, studies on the preparation of organic/inorganic composite hydrogel through blending hemicellulose with nanoparticles are also introduced. Finally, applications of hemicellulose - based hydrogels in the future are prospected.
