    "content": "The hydrophilic monomer 2-acrylamide-2-methylpropane sulfonic acid (AMPS) enhances the hydrophilicity of the film through the introduction of sulfonic acid functional groups, while hydroxyl groups from 3-(trimethoxysilyl)propyl-2-methyl-2-methacrylate (MPS) and tetraethylorthosilicate (TEOS) further increase interactions with water by allowing water to penetrate and swell the film, contributing to hydrophilicity and mechanical properties.The monomers used for synthesizing hydrophilic polymers include acrylic acid (AA), 2-hydroxyethyl acrylate (HEA), and 2-acrylamido-2-methylpropane sulfonic acid (AMPS), which feature carboxylic acid, hydroxyl, and sulfonic acid functional groups respectively, enhancing hydrophilicity by increasing water interactions through hydrogen bonding and ionic interactions.The hydrophilic polymers are synthesized using monomers that contain functional groups such as carboxylic acid (from AA), hydroxyl (from HEA), and sulfonate (from AMPS), which enhance the polymers' hydrophilicity by providing polar interactions and increasing water affinity through hydrogen bonding and ionic interactions."
