    "content": "The monomers used for synthesizing hydrophilic polymers include poly(dimethylaminoethyl methacrylate) (PDMAEMA) and poly(sulfobetaine methacrylate) (PSBMA), where PDMAEMA enhances interactions with water through hydrogen-bond and electrostatic interactions due to its amine functional groups, and PSBMA improves hydrophilicity through its zwitterionic nature, which allows it to regulate water interactions and may lower the freezing point of water.The monomers used for synthesizing hydrophilic polymers include 2-(dimethylamino)ethyl methacrylate (DMAEMA) and sulfobetaine methacrylate (SBMA), where the zwitterionic functional groups in SBMA enhance interactions with water through stronger hydrogen bonding compared to other polymers like PEG."
