摘要: Abstract Zwitterionic coatings with high transparency were developed by combining poly(methacryloxyethylsulfobetaine-co-hexafluorobutyl methacrylate-co-allyl methacrylate) (P(SBMA-co-FMA-co-AMA)) different contents of oligoethylene glycol dimethacrylate (OEGDMA) via UV curing for antifogging and anti-icing applications. The prepared exhibited excellent behavior under moist conditions owing to the hydrophilic hygroscopic capacities coating. Water droplets on zwitterionic 2% OEGDMA demonstrated maximal freezing delay time (126.3 ± 4.0 s) at −18 °C in comparison bare aluminum (about 3 s). Results differential scanning calorimetry analysis further confirmed that bond water non-freezable could be main factors contributing antifogging/anti-icing performances. It was assumed SBMA component coating generate an aqueous lubricating layer performances, while hydrophobic FMA introduced modulation surface wettability coatings. a potential candidate
