    "content": "The text mentions that functional groups such as hydroxyl groups in acrylics (AY) and epoxy groups (EP) enhance the hydrophilicity of the corresponding polymers by providing sites for hydrogen bonding, which increases the interaction with water.The synthesis of hydrophilic polymers often involves functional groups such as hydroxyl (-OH) and amine (-NH2) groups, which enhance hydrophilicity by increasing the polymer's ability to form hydrogen bonds with water molecules, thereby improving interactions with water and allowing for better absorption and retention of moisture.The monomer structure used for synthesizing hydrophilic polymers includes isocyanates and hydroxyl compounds, with the strong polar urethane groups enhancing hydrophilicity by increasing interactions with water through hydrogen bonding.The synthesis of hydrophilic polymers often involves functional groups such as hydroxyl (-OH) and amine (-R-NH-) groups introduced through chemical treatments, which enhance hydrophilicity by increasing polarity and allowing for better interaction with water molecules, thereby improving wettability and surface adhesion.聚酯表面导入了羟基，增强了与涂料官能基的作用，从而提高了聚酯薄膜的亲水性，羟基通过氢键与水分子形成较强的相互作用，进一步增强了与水的亲和力.The hydrophilic polymers are synthesized using monomers such as methacrylic acid, methacrylic acid butyl ester, hydroxyethyl methacrylate, and acrylic acid, with functional groups like hydroxyl (-OH) in hydroxyethyl methacrylate enhancing hydrophilicity by promoting hydrogen bonding and increasing interactions with water.The polyurethane coatings utilize hydroxyl groups (-OH) in the main agent and urethane linkages (-NHCOO-) that enhance hydrophilicity due to their ability to form hydrogen bonds with water, facilitating better interactions with moisture and improving the overall performance of the polymer in its applications.The hydrophilic polymers are synthesized using monomers such as epoxy acrylate, polyurethane acrylate, polyester acrylate, and polyether acrylate, with functional groups that enhance hydrophilicity, such as those found in low, medium, and high functionality acrylate monomers, which affect the reaction rate and properties of the films formed, enabling better interaction with water due to their ability to form hydrogen bonds and increase surface energy.The text does not provide any information regarding the monomer structures used for synthesizing hydrophilic polymers, including details about functional groups that enhance hydrophilicity or explanations of how these functional groups enhance interactions with water.The monomer structures used for synthesizing hydrophilic polymers include saturated end-carboxylated polyester resins, which contain carboxyl groups that enhance hydrophilicity by forming strong hydrogen bonds with water molecules, leading to improved solubility and interaction with the aqueous environment.丙烯酸树脂由丙烯酸酯或甲基丙烯酸酯与其他不饱和单体共聚而成，含有的羧酸官能团增强了聚合物的亲水性，从而提高了与水的相互作用。The hydrophilic epoxy resin incorporates functional groups such as hydroxyl groups and ether links, which enhance its hydrophilicity by providing high polarity, allowing the resin molecules to generate electromagnetic attraction at interfaces, while the epoxy groups can react with free radicals on surfaces to form chemical bonds.The text excerpt does not provide information regarding the monomer structures or functional groups that enhance the hydrophilicity of polymers."
