摘要：PDMS-TiO2-SiO2 hybrid coatings have been prepared on glass substrates via sol-gel method. The structural evolution of the coatings containing different PDMS amounts was examined by TG-DTA and FTIR. It was found that the hybrid character of coatings can be reserved after heating at 200 degrees C. The alkali resistance of hybrid coatings in 1 N NaOH solution at 50 degrees C was investigated by X-ray fluorescence analysis, weight loss and scanning electron microscopy. The results showed that the coating could resist effectively the alkali attack for 24 h. Such alkali resistance depended on the added amount of PDMS and the coating with 20 wt.% PDMS showed a better alkali resistance. (C) 2007 Elsevier B.V. All rights reserved.
