    "content": "The monomers used for synthesizing hydrophilic polymers include poly(ethylene glycol) (PEG), polyacrylic acid, polyvinylpyrrolidone, and hydroxyethylmethacrylate (HEMA), with functional groups such as hydroxyl and quaternary ammonium groups enhancing hydrophilicity by increasing the polar character and enabling hydrogen bonding interactions with water molecules, thus facilitating the formation of a continuous water film and reducing fogging.The synthesis of hydrophilic polymers involves monomers such as sulfobetaine methacrylate (SBMA) and 2-hydroxyethyl methacrylate (HEMA), which contain functional groups like sulfonate and hydroxy groups that enhance hydrophilicity by promoting hydrogen bonding and ion-dipole interactions with water."
