Abstract
A method for surface modification of a fluorine resin by irradiating the surface of the fluorine resin containing a heat-resistant light-absorbing polymeric material and/or a light-absorbing material is with laser light. Surface properties of the fluorine resin molded articles, particularly adhesion and wetting properties, can be greatly improved by a simple operation with high efficiency.
