Abstract:
PURPOSE: A method for modifying the surface of polymer-based substrate for the deposition of a gold thin film is provided to improve interface adhesion between a gold thin film formed on the surface of the polymer-based substrate and a substrate. CONSTITUTION: A method for modifying the surface of polymer-based substrate for the deposition of a gold thin film comprises the steps of: introducing a -COOH functional group to the surface of a polymer-based substrate for depositing the gold thin film; activating the introduced -COOH functional group; and introducing an -SH functional group to the surface of the polymer-based substrate using the activated -COOH functional group.
