Abstract:
A method of providing a film of amphiphilic molecules on the surface of a magnesium fluoride substrate comprising the steps of: applying to said surface a metal oxo-acid solution that is condensable to a metal oxide film whose surface hydrolyzes in the presence of airborne moisture to form hydroxy groups; heating the substrate to condense the metal oxo-acid to a metal oxide film, cooling the substrate, exposing the metal oxide film to airborne moisture to hydrolyze the surface of the metal oxide film and form hydroxy groups thereon, applying to the metal oxide film a material containing amphiphilic molecules that react with hydroxy groups, and allowing the amphiphilic molecules to bond to the metal oxide film by reacting with the hydroxy groups on the metal oxide film and to self-assemble into a substantially continuous film.
