Abstract:
A method for producing a chemically adsorbed film 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; andcontacting the surface of the polymer substrate on which the hydrophilic group is produced with a chemical adsorption solution containing a chlorosilane-containing chemical adsorbent and a nonaqueous solvent, and reacting the hydrophilic group of the polymer substrate with a chlorosilyl group of the chlorosilane-containing chemical adsorbent for forming a covalent bond, thereby forming a chemically adsorbed film on the surface of the polymer substrate,wherein the polymer substrate is made of a material selected from the group consisting of polyimide, polyethersulfone and polyetheretherketone,wherein the ultraviolet laser light is selectively irradiated onto a predetermined part of the surface of the polymer substrate.
