    "content": "The synthesis of the hydrophilic polymer involves the use of acrylic compounds containing trimethyl ammonium groups and polyethylene glycol diamine, which enhance hydrophilicity through the presence of quaternary ammonium structures that facilitate strong interactions with water due to their ionic nature and ability to form hydrogen bonds.The synthesis of hydrophilic polymers involves introducing functional groups such as carboxyl, amino, thiol, hydroxyl, ionic groups like carboxylate, sulfonate, quaternary ammonium, phosphate, and ethoxy units, which enhance hydrophilicity by enabling hydrogen bonding and ionic interactions with water, leading to the formation of a uniform water film that prevents the scattering of light and achieves anti-fog properties.The synthesis of the hydrophilic polymer involves monomers such as di-functional polyether amines and multi-functional acrylates, with ethoxy units serving as hydrophilic functional groups that enhance water interactions by facilitating hydrogen bonding and increasing water absorption, leading to improved hydrophilicity and fog-repellent properties of the resultant polymer.The monomers used for synthesizing hydrophilic polymers include ethoxylated trimethylolpropane triacrylate (EO35mol) with a hydroxyl functional group and ethoxylated pentaerythritol tetraacrylate (EO120mol), both of which enhance hydrophilicity due to the presence of ether (–O–) linkages and hydroxyl (–OH) groups that can form hydrogen bonds with water, thus enhancing interactions with water."
