A multifunctional and environmentally-friendly method to fabricate superhydrophilic and self-healing coatings for sustainable antifogging

Antifogging films are essential in many areas, such as eyeglasses, windshields, goggles and so on. In this work, a transparent antifogging film was successfully prepared on glass by spin-coating a mixture of poly(acrylic acid) (PAA), carboxymethyl cellulose (CMC) and iron (III) chloride hexahydrate (FeCl3·6H2O). The coated film was superhydrophilic and showed excellent anti-frosting and self-healing properties. The composite coating was...
