Method for producing a chemically adsorbed film

摘要

According to the present invention, a method for producing a chemically adsorbed film is provided. The method includes the steps of: irradiating a surface of a polymer substrate with ultraviolet laser light so as to produce a hydrophilic group on the surface of the polymer substrate; and contacting a chemical adsorption solution containing a chlorosilane-based chemical adsorbent and a nonaqueous solvent and the polymer substrate on which the hydrophilic group is produced; and reacting the hydrophilic group of the polymer substrate with a chlorosilyl group of the chlorosilane-based chemical adsorbent for forming a covalent bond, thereby forming a chemically adsorbed film on the surface of the polymer substrate.
