    "content": "The monomers used for synthesizing hydrophilic polymers include poly(vinyl alcohol) (PVA) containing numerous hydroxyl groups (-OH), as well as poly(acrylic acid) (PAA) with carboxylic acid (-COOH) groups, both of which enhance the hydrophilicity of the corresponding polymers by enabling strong hydrogen bonding and increasing affinity for water molecules, thus promoting better intermolecular interactions with water and improving the antifogging properties.The monomer used for synthesizing hydrophilic polymers is Poly(vinyl alcohol) (PVA), which contains hydroxyl (–OH) functional groups that enhance the hydrophilicity of the polymers by increasing their ability to form hydrogen bonds with water, thereby facilitating better interactions and dispersion in aqueous environments.The hydrophilic polymers synthesized in the excerpt utilize polyvinyl alcohol (PVA) and silica (SiO2) as the primary monomer components, where the hydroxyl functional groups in PVA enhance hydrophilicity by forming hydrogen bonds with water molecules, thus increasing water interactions."
