    "content": "Hydrophilic polysaccharides such as chitosan, alginate, hyaluronic acid, and carboxymethyl cellulose contain functional groups that enhance hydrophilicity through their ability to form hydrogen bonds with water, thus increasing interactions with water and leading to long-lasting antifog coatings.The synthesis involved Dimethylaminoethyl methacrylate (DMAEMA), which contains a dimethylamino group that enhances the hydrophilicity of the corresponding polymer by increasing interactions with water through hydrogen bonding and ionic interactions.The monomer used for synthesizing the hydrophilic polymer 14QAS includes dimethylaminoethyl methacrylate (DMAEMA), which possesses functional groups such as the dimethylamino group (-N+(CH3)2) and the methacrylate group (-C(=O)O-), enhancing hydrophilicity through ionic and polar interactions with water molecules, allowing for increased water solubility and hydration."
