Method of duplicating nano pattern texture on object's surface by nano imprinting and electroforming
Publication number: 20130192994Abstract: Disclosed is a method of duplicating a nano-pattern texture of the surface of an object through electroforming using an imprint mold, including selecting the object having the surface texture to be duplicated; disposing the selected object and pre-treating the surface thereof; nano-imprinting the surface of the pretreated object, thus duplicating it on a plastic mold; metallizing the surface of the plastic mold through vapor deposition, and performing electroforming, thus manufacturing metal module master molds; trimming the edges of the metal module master molds, performing micro-processing, connecting the metal module master molds, and then performing electroforming, thus manufacturing a large-area metal unit master mold; and electroforming the metal unit master mold, thus producing a duplicate having the surface texture, thus exhibiting an effect in which the skin of a selected natural object can be duplicated on metal having a uniform thickness.Type: ApplicationFiled: December 22, 2009Publication date: August 1, 2013Applicant: EMOT CO., LTD.Inventors: Kyung Wook Lee, Kyung Yul Lee, Jun Sang Jeong -
Patent number: 8422848Abstract: Provided are a structure color of photonic crystals in which a new structure of a structure color of photonic crystals is provided so that a nanoimprint process can be performed and mass productivity is improved, a method of manufacturing thereof, and a manufacturing apparatus thereof. The method of manufacturing a structure color of photonic crystals includes: forming a plurality of basic element layers by using nanoimprinting, the plurality of basic element layers comprising a plurality of basic unit bodies each having a symmetrical cross-section and thin film connecting portions connecting the basic unit bodies! sequentially stacking the basic element layers! removing the thin film connecting portions by using etching; and determining whether the structure color of photonic crystals is completed, wherein, when it is determined that the structure color of photonic crystals is not completed, the forming, the stacking, and the removing are repeatedly performed.Type: GrantFiled: July 9, 2008Date of Patent: April 16, 2013Assignee: Emot Co., LtdInventors: Kyung Wook Lee, Kyung Yul Lee, Bong Yul Lee, Wayne H.
