  • Method of forming self-assembled, mono- and multi-layer fullerene film and coated substrates produced thereby
    Patent number: 5338571
    Abstract: A method is provided for forming a fullerene layer on a substrate by chemically treating a surface of the substrate to provide a bond-forming species at the surface effective to covalently bond with fullerenes in solution and contacting the treated substrate surface with a solution of fullerenes to form a fullerene layer covalently bonded to the treated substrate surface. Alternately or in addition, a fullerene layer is formed on a substrate by chemically modifying fullerenes to provide a bond-forming species thereon, chemically treating a surface of the substrate to provide a bond-forming species effective to covalently bond with the bond-forming species of the fullerenes in solution, and contacting a solution of treated fullerenes with the treated substrate surface to form a fullerene layer covalently bonded to the treated substrate surface.
