    "content": "Super-hydrophilic coatings have a very low contact angle, less than 5 degrees, indicating that they contain functional groups that enhance hydrophilicity, allowing water condensed on these surfaces to spread out quickly without the need for surfactants to be extracted, unlike Type II coatings which rely on surfactants to lower surface energy.The monomer used for synthesizing hydrophilic polymers is monomethyl ether polyethylene glycol (mPEG), which contains ether functional groups that enhance hydrophilicity by providing polar sites that facilitate interactions with water through hydrogen bonding.The text describes the use of monomers such as mPEG triethoxysilane, 3-(trimethoxysilyl)propyl acrylate, and 3-(trimethoxysilyl)propyl methacrylate, which contain hydrophilic functional groups such as ethylene glycol units and methacrylate groups that enhance interactions with water by promoting hydrogen bonding and increasing water solubility.The synthesis of hydrophilic polymers involved using monomers such as polyethylene glycol diacrylate and sulfopropyl acrylate potassium salt, where functional groups like the ether groups in polyethylene glycol and the sulfonate groups in sulfopropyl acrylate enhance hydrophilicity by forming strong hydrogen bonds with water molecules, thereby increasing interactions with water."
