Title:
NANOSTRUCTURED FORMS AND LAYERS AND METHOD FOR PRODUCING THEM USING STABLE WATER-SOLUBLE PRECURSORS
Document Type and Number:
WIPO Patent Application WO1999052964
Kind Code:
A3
Abstract:
The invention relates to a method for producing a composition for preparing nanostructured forms and layers, consisting of bringing an aqueous and/or alcoholic sol of a compound of an element selected from silicon and the main and sub-group metals into contact with species which have hydrolyzable alkoxy groups and which include at least one organically modified alkoxysilane or a precondensate derived therefrom, in conditions which lead to the (further) hydrolysis of the species and then removing any alcohol which has formed or which may optionally have been present originally. The invention is characterized in that enough alcohol is removed to leave a residual amount of not more than 20 wt.% in the composition.
