| Résumé : |
Sorbitol is a naturally occurring sugar alcohol and this work focuses on sorbitol-based UV curable polyurethane coatings for antifog, antifrost, and self-cleaning applications. The resins were synthesized by reacting isophorone diisocyanate (IPDI) with varying proportions of sorbitol and polyethylene glycol (PEG200). The resins synthesized were characterized by FTIR, 1H NMR, and analytical techniques such as hydroxyl, iodine, and acid values. Various formulations were prepared using the developed resin, reactive diluents, and photoinitiator. The coatings were applied on silane-treated glass substrates and then cured under UV light. The hydrophilicity of coatings was investigated by water contact angle measurement. The antifog, antifrost, and self-cleaning tests were carried out and it was observed that the coating shows antifog property for a contact angle below 33° but antifrost effect was shown by the coatings with a contact angle less than 7°. Owing to the excellent hydrophilicity, the black stains of oil were washed out with ease under a water flow, hence showing excellent oil repellent/self-cleaning property as well. |
