    摘要: A method of forming a hybrid physically and chemically cross-linked double-network hydrogel with highly recoverable and mechanical properties in a single-pot synthesis is provided. The method comprises the steps of combining the hydrogel precursor reactants into a single pot. The hydrogel precursor reactants include water; a polysaccharide; a methacrylate monomer; an ultraviolet initiator; and a chemical crosslinker. Next the hydrogel precursor reactants are heated to a temperature higher than the melting point of the polysaccharide and this temperature is retained until the polysaccharide is in a sol state. Then the single-pot is cooled to a temperature lower than the gelation point of the polysaccharide and this temperature is retained to form a first network. Thereafter, photo-initiated polymerization of the methacrylate monomer occurs via the ultraviolet initiator to form the second network.
