    "content": "The monomer used for synthesizing the hydrophilic polymer in this study is N,N-dimethylacrylamide (DMAA), which contains functional groups that enhance hydrophilicity, and these groups increase interactions with water by facilitating hydrogen bonding and reducing the contact angle, as evidenced by a decrease to below 40 degrees after the water gel coating application.The hydrophilic polymers are synthesized using N,N-dimethylacrylamide, which contains amide functional groups that enhance hydrophilicity by providing polar sites for hydrogen bonding with water molecules, thereby improving water interactions."
