摘要：5n7 A durable and extremely water- and oil repellent ultra thin film is formed on the surface of a substates such as glass, ceramics, fabrics, fur and cloth by areaction rate
dehydrochlorination reaction between a functional group such as a hydroxyl group or an
imino group on the surface of the substrate. The coating film of the material comprises a plurality of chlorosilyl groups was formed on the surface of the substrate by dipping and holding the substrate comprising functional groups on its surface in a solution prepared by dissolving a material comprising fluorocarbon groups and a plurality of chlorosily groups in a non-aqueous solvent and drying the substrate which is then taken out from the solution in a substantially moistureless or low moisture atomosphere and removing the non-aqueous solvent remaining on the substrate. Further, when the coating film is left in an atomosphere comprising moisture, i.e., humid air, the coating film is polymerized by a dehydrochlorination reaction between the coating film and the moisture in the atomosphere. The film is formed on the surface of the substrate containing hydroxyl groups, imino groups or carboxyl groups through -SiO- bonds or -SiN< bonds.
