    "content": "The polydimethylsiloxane (PDMS)-poly(ethylene glycol) (PEG) copolymer and zwitterionic poly(sulfobetaine methacrylate) (PSBMA) used in amphiphilic coatings enhance hydrophilicity through their water-absorbing PEG chains and zwitterionic components, which facilitate strong electrostatic and hydrogen-bond interactions with water, thereby promoting water absorption and forming a lubricating aqueous layer that improves antifogging and anti-icing performances.The monomers used for synthesizing hydrophilic polymers include DMAEMA and SBMA, where the functional groups such as the zwitterionic moiety in SBMA and the ammonium groups in PDMAEMA enhance the hydrophilicity by enabling stronger hydrogen bonding with water molecules compared to other surfaces like PEG."
