METHOD FOR FORMING ULTRA-WATER-REPELLING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To develop ultra-water-repellency by forming microscopic irregular structure on the surface by a simple and inexpensive method without necessitating particular apparatus and technique. SOLUTION: The method for forming an ultra-water-repelling structure comprises a step to form a prescribed form such as a sheet of a composite material obtained by mixing and dispersing fine particles of a water-repelling resin in a base polymer, and a step to form protrusions of the fine particles of the water-repelling resin by dissolving only the base polymer on the surface of the formed article obtained by the forming step with a solvent capable of selectively dissolving the base polymer to expose the fine particles of the water-repelling resin on the surface of the formed article. Further excellent ultra-water-repellency can be realized by forming a formed article using a mold having fine irregularity on the inner surface. COPYRIGHT: (C)2007,JPO&INPIT
