Chemically adsorbed film and method of manufacturing the same.

摘要

A chemically adsorbed monomolecular or a laminated monomolecular film comprising a monomolecular film formed on said substrate surface by covalent S-bonds is disclosed. For example, the covalent S-bond is selected of a group consisting of -(S=O)- and -(O=S=O)-. A method of producing a chemical adsorption film comprising; contacting a substrate containing hydroxl groups present on the surface with a non-aqueous solvent containing a material having a thionyl halide group or sulfuryl haloride group; removing unreacted surface active material remaining on the substrate by washing the substrate with a non-aqueous organic solution for making monomolecular a precursor film; reacting unreacted surface active material remaining on the adsorbed monomolecular precursor film with water; and drying the adsorbed monomolecular film is also disclosed. Further, a method of producing a laminated chemical adsorption film comprising laminating a monomolecular adsorption film by repeating the above steps is disclosed.
