Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method of producing glass having an uneven shape on the surface which enables formation of a fine and regular uneven shape composed of an inorganic material at low costs on the surface of glass of a large area.SOLUTION: A method of producing glass having an uneven shape comprises filling recessed parts 21 of a film 2 which has an uneven shape 4 and serves as a casting mold with a sol liquid 1 consisting of tetraethoxysilane, an alcohol, an acid and water, transferring the sol liquid 1 to the surface of glass 3 by putting the film 2, with the recessed parts 21 filled with the sol liquid 1, on the surface of glass 3, leaving standing in the state until the sol liquid 1 solidifies and removing the film 2 from the surface of the glass 3 to form a fine and regular uneven shape 4 composed of an inorganic material on the surface of the glass 3.
【課題】大きな面積のガラスの表面に無機材料からなる微細な規則的な凹凸形状を低コストで形成することが可能な表面に凹凸形状を有するガラスの製造方法を提供する。【解決手段】テトラエトキシシラン、アルコール類、酸及び水からなるゾル液1を、鋳型である凹凸形状4を有するフィルム2の凹部21に充填し、凹部21にゾル液1を充填したフィルム2をガラス3の表面に載置することによりゾル液1をガラス3の表面に転写するとともに、この状態でゾル液1が固化するまで放置し、その後、ガラス3の表面からフィルム2を除去することにより、ガラス3の表面に無機材料からなる微細な規則的な凹凸形状4を形成する。【選択図】図1 |
