Abstract
Abstract Polysaccharides possessing distinctive properties, such as biocompatibility, biodegradability, and nontoxicity, are promising matrices for hydrogels. However, the polysaccharides‐based hydrogels have poor mechanical properties, which is a major limitation for their applications. In recent years, researches on double‐network (DN) hydrogels with outstanding mechanical properties have gained increasing attention. Therefore, the main research orientation is to combine the benefits of both materials and broaden their applications in various fields. This paper reviews the recent progress of polysaccharide‐based DN (PDN) hydrogels that show great advantages in mechanical, physiochemical properties, biocompatibility, biodegradability and so on. The preparation, structure, and unique properties of different PDN hydrogels are discussed in detail. Moreover, we summarize the applications of PDN hydrogels in biomedical and energy storage and conversion fields. This research progress is breaking through the limitations of PDN hydrogels and opening a new avenue for their future development.
