ABSTRACT:
A chemically adsorbed film is formed on a substrate surface as a coating film, in which film-composing molecules are inclined in a preferable direction and are bonded and fixed to the substrate surface in a predetermined single direction and at one end. A coating film with excellent anti-abrasion properties is provided by adding the same type of a crosslinking agent as a chemical adsorbent in a chemical adsorption solution in film-forming processes, and then by crosslinking adsorbed molecules. 5 wt. % of CF.sub.3 (CF.sub.2).sub.7 (CH.sub.2).sub.2 SiCl.sub.3 (chemical adsorbent), 3 wt. % of hexachlorodisiloxane (crosslinking agent), and 92 wt. % of cyclohexane (nonaqueous solvent; bp. 80.degree. C.) are mixed so as to prepare a chemical adsorption solution. The solution is coated on an aluminum substrate in a dry atmosphere, and the solvent is evaporated and removed from the substrate. Thus, a polymer coating film is formed in which molecules are entangled and crosslinked and are covalently bonded to the substrate surface.
