    "content": "The synthesis of hydrophilic polymers in this study involved the monomer N,N-dimethylacrylamide (DMAA), which contains amide functional groups that enhance the hydrophilicity of the corresponding polymers, as these amide groups can form hydrogen bonds with water molecules, promoting interactions with water and resulting in a reduced contact angle of the coated surface from above 80 degrees to under 40 degrees after application of a thin hydrogel layer.The synthesis of hydrophilic polymers involves the use of N,N-dimethylacrylamide, which contains amide functional groups that enhance the hydrophilicity of the resulting polymers by forming hydrogen bonds with water molecules, thus increasing their affinity for water."
