    "content": "The monomers used for synthesizing hydrophilic polymers include Chitosan (CHI), which contains amino (-NH2) and hydroxyl (-OH) functional groups, and Carboxymethyl cellulose (CMC), which has carboxyl (-COOH) and hydroxyl (-OH) groups; these functional groups enhance hydrophilicity by increasing hydrogen bonding capacity and enabling strong interactions with water molecules, contributing to the overall water affinity of the resulting polymers."
