Scientists of TIPC report a facile one-step approach to construction of antifogging and frost-resisting coatings on flexible substrates from poly(vinyl alcohol) (PVA). Excellent antifogging and frost-resisting properties were observed, and are derived from the hydrophilicity and hygroscopicity of coatings. The coatings are highly transparent, and the average transmittance of coatings increases with increase of the concentration of PVA aqueous solution.
