    "content": "The synthesis of hydrophilic polymers includes the use of monomers with functional groups such as hydrophilic quaternary ammonium groups, which enhance hydrophilicity by enabling better interactions with water through hydrogen bonding and ionic interactions.The monomers used for synthesizing the hydrophilic polymers include 2-(Dimethylamino)ethyl methacrylate (DMAEMA) and acrylic acid (AA), both of which contain functional groups such as amino groups (-N(CH3)2) in DMAEMA and carboxylic acid groups (-COOH) in AA that enhance hydrophilicity by creating strong hydrogen bonding interactions with water molecules, thereby increasing the affinity of the resulting polymers for water."
