Novel high-performance anti-fog coating
Scientists have developed a novel organic-inorganic zwitterionic acrylate polymer for high-performance anti-fog coating.

The organic-inorganic zwitterionic polymer endows the coating on polycarbonate substrate with excellent anti-fog/frost performance. Image source: ElbRose - Pixabay (symbol image).
-A novel organic-inorganic zwitterionic polymer was developed via free radical copolymerisation using quaternary ammonium salt as hydrophilic monomer.
The unique structure realises a compromise between the hydrophobicity and hydrophilicity. The chemical composition, the physical properties, the anti-fog characteristic and mechanism of the zwitterionic acrylate coating were investigated by FT-IR, UV-VIS spectrometry, XPS, AFM and water contact angle.
Excellent anti-fog/frost performance
The organic-inorganic zwitterionic polymer endows the coating on polycarbonate (PC) substrate with excellent anti-fog/frost performance, good adhesion and stability (repeated use for 100 times) under wider temperature range (−40 ∼ 80 °C) of applications.
The study has been published in Progress in Organic Coatings, Volume 142, May 2020.
