POLYMER MATERIAL AND ITS SURFACE MODIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a surface modification method of a polymer material which can markedly improve surface properties of the polymer material through a new process that quite differs basically from the conventional surface modification method, and to provide a polymer material having a modified surface that is obtained by the method. SOLUTION: The surface modification method of a polymer material comprises irradiating specified ultra-violet light onto the surface of the polymer material in the presence of an aromatic substance, and preferably in the presence of a photocatalyst-containing layer. The polymer material having improved surface properties (e.g. friction coefficient) is obtained by the method. COPYRIGHT: (C)2005,JPO&NCIPI
