    "content": "The hydrophilic monomers used for synthesizing super-hydrophilic polymers include acrylic acid, poly(ethylene glycol) monomethacrylate, and 2-(methacryloyloxy) ethyl phosphorycholine, which enhance hydrophilicity through functional groups such as carboxylic acid (-COOH) in acrylic acid and ethylene glycol units (-O-), enabling strong hydrogen bonding and dipole interactions with water, thereby promoting water absorption and spreading.The monomer 2-Methacrylatoethyl trimethyl ammonium chloride contains a quaternary ammonium group that enhances the hydrophilicity of corresponding polymers due to its positive charge, which facilitates strong ionic interactions with water."
