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.
