MEMBER HAVING WATER-REPELLENT AND OIL-REPELLENT ANTIFOULING PROPERTY SURFACE, AND MANUFACTURING METHOD OF THE WATER-REPELLENT AND OIL-REPELLENT ANTIFOULING PROPERTY SURFACE

摘要

PPROBLEM TO BE SOLVED: To realize a highly water-repellent and oil-repellent antifouling property surface having a droplet contact angle to silicone oil of about 110 or more, in relation to a fixture developed to carry out a Marangoni convection experiment in a space station without any gravity action. PSOLUTION: The surface is machined to form big protrusions/recesses and small protrusions/recesses by a process of blast-processing or dimple-processing at least the surface, a process of chemical-etching or electrolytic-etching, and a process of forming a water-repellent and oil-repellent antifouling property thin film. The member has a super water-repellent and oil-repellent surface in which each surface is covered with the water-repellent and oil-repellent antifouling property thin film, and its manufacturing method is provided.
