    "content": "The monomer polyvinyl alcohol (PVA), characterized by its intrinsic hydrophilicity due to hydroxyl functional groups, enhances interactions with water through hydrogen bonding interactions, which contribute to the material's stable swelling properties and overall performance in oil-water separation applications.The monomer structures used for synthesizing hydrophilic polymers include poly(vinyl alcohol) (PVA) and plant-derived polyphenol TA, with functional groups such as hydroxyl (-OH) on PVA and phenolic groups in TA that enhance the hydrophilicity of the polymers through strong hydrogen bonding interactions with water.The monomers used for synthesizing hydrophilic polymers include Polyvinyl Alcohol (PVA) and Tannic Acid (TA), wherein the hydroxyl groups (-OH) in PVA and the multiple phenolic hydroxyl groups in TA enhance the hydrophilicity of the resulting polymers by facilitating hydrogen bonding with water molecules."
