Abstract
In a surface treatment method of treating the surface of a material to be treated, by irradiating with light the material to be treated and a mediating material in contact with each other, the mediating material itself causes substantially no interaction upon irradiation with light. The surface of the material to be treated is treated by provision of a chemical reaction field, in which a substituent of the material to be treated and an atom of atomic group of the mediating material is induced by excitation, by irradiating with light by using the logical product of the contact interface between the material to be treated and the mediating material and the light irradiation region, thereby causing and progressing bonded state transition.

A method for treating a surface of a member comprising:
- irradiating with light a field including an interface between the member and a mediating material so that an atom or an atomic group of the member and an atom or an atomic group of the mediating material at the interface are excited for substitution of the atom or the atomic group of the member by the atom or the atomic group of the mediating material, thereby treating the surface of the member,
- wherein the mediating material causes substantially no interaction upon irradiation with light when used separately from the member.
A method for treating a surface of a member having a carbon atom singly bonded to a hydrogen atom on the surface, the surface being in contact with a liquid mediating material, which is an aggregate of a polymer having on a main chain thereof an ether bonding group and a carbon fluoride CnFm (n=1, 2, 3, . . . , m=2n or 2n+1) group, the method comprising:
- irradiating a field including the surface of the member in contact with the liquid mediating material with ultraviolet radiation having a wavelength of 221.4 to 351.6 nm so as to substitute the hydrogen atom singly bonded to the carbon atom on the surface of the member with the carbon fluoride group of the liquid mediating material, thereby modifying the surface of the member.
