ABSTRACT

Abstract Preparation of hydrogels based on polysaccharides, including starch, cellulose, chitosan, carrageenan, sodium alginate, hyaluronic acid, and their derivatives, has attracted a great deal of attention due to their unique properties, such as biocompatibility, biodegradability, environmental friendliness, and nontoxicity. In comparison with the traditional physical and chemical cross-linking methods, high-energy (γ-ray or electron beam) irradiation-induced cross-linking can be efficiently achieved at room temperature and atmospheric pressure without additional initiators, and has been widely investigated for the preparation of hydrogels. Meanwhile, radiation-induced grafting and cross-linking of functional vinyl monomers onto natural polysaccharides to prepare hydrogel is also a promising technique to impart desirable functionality and performance. In this chapter, we describe different polysaccharide-based hydrogels prepared via the radiation method and their potential applications in various fields.
