Preparation of Self-Healing Antifogging Hard Coatings Using Carboxy-Functionalized Polysilsesquioxanes and Oligo(ethylene glycol)s.

ABSTRACT: Water-resistant antifogging hard coatings possessing self-healing properties were successfully prepared by applying N,N-dimethylformamide solutions containing the mixtures of carboxy-functionalized polysilsesquioxane (PSQ-2C) with oligo(ethylene glycol)s (OEGs; n = 2-6 and n = 2-4) at the feed functional group ratios (carboxy groups in PSQ-2C/hydroxy groups in OEG) of 10:1 and 4:1, respectively, onto oxygen plasma-treated glass substrates, followed by heat drying, water immersion, and room-temperature drying. The formation of ester bonds in the resulting coatings, indicating the presence of a cross-linked structure, was confirmed via Fourier-transform infrared/attenuated total reflectance spectroscopy. Notably, the coating prepared using PSQ-2C and tetraethylene
