ADSORBED MONOMOLECULAR FILM AND METHOD OF MANUFACTURING THE SAME

摘要

The invention seeks to provide a method of forming a monomolecular film of fluorine-containing molecules on a substrate surface such that the film has an uniform thickness with minimal surface irregularities and is substantially pin hole free. The invention also provides for a substrate obtained by using the same method which has excellent water-and oil-repelling, anti-fogging, and anti-contaminating properties. The monomolecular film is formed on the substrate surface either directly or via a given protective film. The monomolecular film coating is characterized by a plurality of different chlorosilane-based surface active materials which are different in molecular length have a fluorine group. The surface irregularities of the film are generally confined to the molecular level.
