Cellulose-based stimuli-responsive and self-healing hydrogels

초록

Cellulose is one of the most abundant biopolymers with special characteristics like biocompatibility, biodegradability, and high hydrophilicity used for the fabrication of hydrogels, and cellulose-based hydrogels are found to be useful biocompatible materials used in various biomedical applications. One of the interesting properties of hydrogels is their response to various external stimuli like physical or chemical forces, electromagnetic fields, ionic strength, etc. In addition, hydrogels with self-healing properties can easily restore breaks and provide considerable benefits to sustain the integrity of network structures as well as their mechanical properties for long-term use. The self-healing hydrogel based on natural resources like cellulose easily degrades in the natural environment and guarantees long-term biosafety compared to other nondegradable self-healing polymers, and thus they are developed rapidly owing to their wide range of bio applications. This chapter gives the state-of-the-art progress of cellulose-based hydrogels and focuses on the following parts: the description of cellulose and hydrogels in terms of their structure and properties, as well as the importance of cellulose as a raw material for the fabrication of hydrogels. The next part is about the details of fabrication methods for cellulose-based stimuli-responsive hydrogels using various stimuli, like physical, chemical, and other stimuli. Next, we highlighted the different methods used for the fabrication of cellulose-based self-healing hydrogels. Further, we also discussed the multifaceted applications of cellulose-based self-healing and stimulus-responsive hydrogels. And in the last part, we describe the future perspectives of cellulose-based self-healing and stimuli-responsive hydrogels. © 2025 Elsevier Inc.
