    "content": "The hydrophilic polymers were synthesized using monomers such as 2-(Dimethylamino) ethyl methacrylate (DMAEMA), which contains a dimethylamino group that enhances hydrophilicity through strong hydrogen bonding with water, and 2-(Methacryloyloxy) ethyl dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA), which has a zwitterionic nature due to the presence of a sulfonic acid group, thereby increasing interactions with water molecules through ionic interactions and dipole interactions."
