ULTRA-WATER-REPELLENT, HIGHLY LUMINOUS, TRANSPARENT MATERIAL AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a novel, ultra-water-repellent, highly luminous material having the surface of a transparent material formed to have a structure that the both a brightness improving performance and high water repellency and is excellent in a mechanical strength. SOLUTION: The ultra-water-repellent, highly luminous, transparent material provided herein has a transparent water repellent layer formed on a transparent base of which the surface is formed of V-shaped grooves consecutive in one direction, of which the vertical angles of projecting and recess parts are 40 deg.-80 deg., of which angles formed by straight lines connecting the vertexes of the right and left projecting parts adjacent to the vertex of the recess part and by the horizontal direction are equally 89 deg. or below on the right and left sides and of which the cycle of the groove is 1μm-2 mm.
