IRREGULARITY UTILIZING FINGERING INSTABILITY, SURFACE HAVING MICRO-IRREGULARITY, ITS IRREGULARITY AND METHOD FOR FORMING MICRO-IRREGULARITY

PROBLEM TO BE SOLVED: To provide a surface treating agent for forming irregularity and micro-irregularity on the surface of a material, treated material, and a surface treating method for forming the irregularity and the micro-irregularity, and to more concretely provide a highly repellent surface treating method that is useful for a highly repellent glass, lens, material of a fiber or the like and a material excellent in anti-contamination capacity, a panel excellent in light scattering property, an illumination of an optical fiber or the like, an antenna, an electric supply cable, a snow cover and protection against snow of a steel tower or the like, an icicle countermeasure material, coating, the formation of irregularity on the surface of a semiconductor substrate and their processing being also easy by forming the micro-irregularity on the surface of a material. SOLUTION: The system is achieved by the surface of an irregularity structure having an irregularity structure with on average 0.1-1.0 mm-distance, further a surface characterized by providing the micro-irregularity structure in a range of cycle of 0.1-50 μm.
