Transparent hydrophobic methyltrimethoxysilane(MTMS)/Si-sol/hydroxypropyl acrylate coatings was prepared in order to improve the hydrophobicity of glass surface.Effects of the hydrolysis temperature of MTMS
the pH value of hydrolization solution
the reaction time of MTMS with Si-sol
and the MTMS content on the hydrophobicity of the coatings were discussed respectively.The type and amount of functional groups on the coating’s surface as well as the microstructure were characterized by Fourier transform infrared spectroscopy(FTIR)and atomic force microscope.The coatings with the best hydrophobicity was found when prepared with the following conditions: the MTMS was hydrolyzed in 40℃
pH=3
and the volume ratio of the hydrolyzed MTMS and Si-sol was 0.1
the reaction time was 2 h and the reaction temperature was 60℃.
