    "content": "The hydrophilic polymers synthesized for antifog coatings utilize functional groups such as hydroxyl groups present in poly(ethylene glycol) (PEG) and surface-active agents like Tween 20, which enhance hydrophilicity by promoting strong hydrogen bonding interactions with water molecules, thereby allowing water droplets to spread and form a continuous film rather than bead up.The monomers used for synthesizing hydrophilic polymers include 2-hydroxyethyl methacrylate (2-HEMA), which contains a hydroxyl functional group that enhances hydrophilicity by forming hydrogen bonds with water molecules, significantly increasing water interactions through strong dipole-dipole interactions."
