    "content": "N-Hydroxyethylacrylamide contains a hydroxyl (-OH) functional group that enhances hydrophilicity by forming hydrogen bonds with water, while quaternary ammonium groups can increase solubility in water due to their charged nature, allowing for stronger ionic interactions with water molecules.The monomers used for synthesizing hydrophilic polymers, such as 2-(Dimethylamino)ethyl methacrylate (DMAEMA), N-(2-hydroxyethyl) acrylamide (HEAA), and 2-Aminoethyl methacrylate hydrochloride (AEMA), contain functional groups like amino (-NH2), hydroxyl (-OH), and quaternary ammonium groups, which enhance the hydrophilicity of the corresponding polymers by promoting hydrogen bonding and ionic interactions with water molecules."
