Abstract:
1. A method for preparing a chemical adsorption film on a surface of a substrate containing active hydrogen, comprising the steps of: treating a metal based surfactant having at least one hydrolyzable group with a metal oxide or a partially hydrolyzed product of at least one metal alkoxide and water in an organic solvent to form a solution, and contacting the solution with the surface of the substrate, wherein said metal alkoxide is selected from the group consisting of titanium alkoxide, zirconium alkoxide, aluminum alkoxide, germanium alkoxide, indium alkoxide, tin alkoxide, tantalum alkoxide, tungsten alkoxide, zinc alkoxide and lead alkoxide, and wherein when a partially hydrolyzed product of a metal alkoxide is used, the amount of the partially hydrolyzed product is 0.001 to 1 mol per mol of the metal based surfactant.
