Preparation and application of cellulose-based hydrogels derived from bamboo

Hydrogels have outstanding research and application prospects in various fields. Among them, the design and preparation of cellulose-based functional hydrogels derived from bamboo have attracted increasing research interest. Cellulose-based hydrogels not only have the skeleton function of hydrogels, but also retain excellent specificity, smart structural design, precise molecular recognition ability, and superior biocompatibility. Cellulose-based hydrogels show important application prospects in various fields such as environmental protection, biomedicine, energy, food packaging and plant agriculture. Recently, researchers have extracted cellulose from bamboo and generated a variety of cellulose-based functional hydrogels with excellent properties by various cross-linking methods. In addition, a variety of multifunctional hybrid cellulose-based hydrogels have been constructed by introducing functional components or combining them with other functional materials, expanding the breadth and depth of their applications. Herein, we elaborate advances in the field of cellulose-based hydrogels and highlight their applications in various fields. Meanwhile, the existing problems and prospects are summarized. The review provides a reference for further development of cellulose-based hydrogels.
