METHOD FOR CONTROLLING HYDROPHILIC AND HYDROPHOBIC PROPERTY OF SURFACE OF SYNTHETIC RESIN MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for freely controlling hydrophilic property and hydrophobic property of the surface of a synthetic resin molded article even in the synthetic resin molded article having integral structure using a same synthetic resin material. SOLUTION: The method for controlling hydrophilic property and hydrophobic property of surface of the synthetic resin molded article comprises a first step for bringing the synthetic resin molded article into contact with a supper critical carbon dioxide containing a specific surfactant and a second step for retaining the synthetic resin molded article after contacting for a definite time under definite environmental conditions.
