Title:

SOLID SURFACE MODIFYING METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/1994/021715

Kind Code:

A1

Abstract:

This method is characterized in that it includes the steps of keeping a surface of a solid material, such as a synthetic resin, glass, a metal and a ceramic material in contact with a liquid compound or a compound solution, applying rays of light selected from ultraviolet rays, visible rays of light and infrared rays to an interface between the surface of the solid material and liquid compound or compound solution so as to optically pump the surface of the solid material and the liquid compound or compound solution, subjecting the chemical species in the liquid compound or compound solution to substitution, and accumulating chemical species or carrying out an etching operation using the chemical species. This method preferably includes the steps of bringing a transparent window member into close contact with the surface of a solid material to be treated, interposing a thin layer of a liquid compound or compound solution between the solid material and window member by utilizing a capillary phenomenon, and applying ultraviolet rays, visible rays or light or infrared rays to the resultant product through the transparent window member. This treatment enables the irradiated portion to have hydrophilic property, adhesive property, printability, corrosion resistance and conductivity.
