摘　　要：水凝胶是一种交联的三维网状亲水性聚合物材料,能够吸收和保留大量的水并且保持一定形状。近年来,随着石油资源的枯竭和人类对环境问题的日益关注,天然或改性类高分子合成聚合物水凝胶已成为研究的热点。纤维素及其衍生物是一大类可再生天然高分子材料,具有无毒、资源丰富以及种类繁多等特点,由它合成的纤维素基水凝胶具有良好的吸水保水性、生物相容性和生物可降解性等,可应用于医疗、环境、农业等多个领域。本文综述了近年来纤维素基水凝胶的构建及应用研究进展,将水凝胶的微观网络结构与宏观性能相结合,重点对比了单网络、互穿网络和半互穿网络纤维素基水凝胶的力学性能、溶胀性能和吸附性能等,并对其在医疗、环境、农业以及电子领域的应用进行总结。对开发兼具力学性能和生物相容性的纤维素基水凝胶以及未来发展更多绿色经济的方法合成纤维素基水凝胶材料并将之用于工业化提出了展望。Hydrogel is a cross-linked three-dimensional network hydrophilic polymer material,which can absorb and retain a large amount of water and maintain a certain shape.In recent years,with the depletion of petroleum resources and the increasing attention of human beings to environmental issues,natural or modified polymer synthetic polymer hydrogels have become a research hotspot.Cellulose and its derivatives are a large class of renewable natural polymer materials,which have the characteristics of rich resources,wide variety,non-toxic and renewable,etc.The synthesized cellulose-based hydrogel has good water absorption,water retention,biocompatibility and biodegradability,etc.,which can be used in medical,environment,agriculture and other fields.The research progress of the construction and application of cellulose-based hydrogels in recent years was reviewed in this paper.The microscopic network structure is combined with the macroscopic properties of the hydrogel.The mechanical properties,swelling properties and adsorption properties of the single network,interpenetrating network and semi-interpenetrating network cellulose-based hydrogels were summarized,and their applications in medical,environmental,agricultural and electronic fields were introduced.The development of cellulose-based hydrogels with both mechanical properties and biocompatibility,and the development of more green economic methods for the synthesis of cellulose-based hydrogels for industrial applications were proposed.
