Chitosan as a Natural Copolymer with Unique Properties for the Development of Hydrogels
Hydrogel-based polymers are represented by those hydrophilic polymers having functional groups in their chain such as amine (NH2), hydroxyl [-OH], amide (-CONH-, -CONH2), and carboxyl [COOH].These hydrophilic groups raise their potential to absorb fluids or aqueous solution more than BRANCHED CHAIN AMINO ACIDS their weights.This physicochemical mec
