Abstract

As to the deposition of multilayer SiO₂ coatings by sol- gel process, in some cases the successive layers have a tendency to be broken during drying. We suggest that microstructure of coating solution and properties of coating surface greatly affect the ability to form multilayer uniform coatings. Factors that affect the ability to form multilayer uniform coatings were studied. These factors were type of catalyst, aging of coating solution, post treatment of previous coatings. In present paper, experimental is described and results are given. Cause of this phenomenon was analyzed. By means of controlling the hydrolysis reaction degree of tetraethyl orthosilicate, thus modifying microstructure of coating solution and properties of coating surface, we succeeded in solving this problem in deposition of multilayer uniform SiO₂ coatings.
