    "content": "The synthesis of hydrophilic polymers such as polyacrylamide-alginate double network hydrogel involves functional groups from polar group-containing epoxies that enhance hydrophilicity through increased interactions with water due to their ability to form hydrogen bonds and facilitate the diffusion and reorganization of polymer chains in an aqueous environment.Monomers such as sodium alginate, acrylamide, and gelatin contain functional groups like hydroxyl (-OH) and amine (-NH2), which enhance the hydrophilicity of the corresponding polymers by forming hydrogen bonds with water molecules, thus increasing their interactions with water.The synthesis of hydrophilic polymers involves the use of acrylamide (AM) and sodium alginate (SA) as monomers, where the presence of carboxylic groups in SA and amide groups in AM enhances hydrophilicity by improving interactions with water through hydrogen bonding and ionic interactions."
