    "content": "The hydrophilic polymer network is composed of poly(vinyl alcohol) (PVA), which contains hydroxyl functional groups that enhance hydrophilicity through hydrogen bonding with water molecules, thereby promoting water absorption and preventing fog formation.The hydrophilic polymer is synthesized using PVA, which contains abundant hydrophilic hydroxyl groups that facilitate the quick spreading and sucking of condensed water, enhancing its interactions with water through hydrogen bonding.The extracted text does not provide specific information regarding the monomer structures or the functional groups that enhance the hydrophilicity of the corresponding polymers."
