Patent number: 10663237Abstract: The present disclosure relates to a heat transfer tube comprising nanostructures formed on the surface, and a method for manufacturing the same, and by forming nanostructures on a heat transfer tube surface, a superhydrophobic surface may be obtained under a high temperature environment as well. In addition, superhydrophobicity may be enhanced by further forming a hydrophobic coating layer on the nanostructure-formed heat transfer tube surface. By using a method of forming nanostructures by dipping the heat transfer tube surface, complex shapes may be coated, and therefore, a plurality of assembled heat transfer tubes may be coated, and damages occurring during a process of assembling the heat transfer tube after coating may be prevented.Type: GrantFiled: March 14, 2018Date of Patent: May 26, 2020Assignees: Doosan Heavy Industries Construction Co., Ltd., UNIVERSITY-INDUSTRY COOPERATION GROUP OF KYUNG HEE UNIVERSITYInventors: Jin Bum Kim, Hyun Sik Kim, Young Suk Nam, Kyoung Hwan Song, Seung Tae Oh, Jae Hwan Shim, Dong Hyun Seo

Patent number: 7985358Abstract: There is provided a process of making a mold for optical films. The process of making a mold for optical films comprises: etching a stereostructure in a surface of the mold having a flat surface or an engraved convex and concave surface, by using a laser beam. The process of making a mold for optical films may be useful to easily mark spots, to control the height of protrusions and the position where the protrusions are formed, and also to form the protrusions having constant depths even in a curved surface such as a convex and concave surface.Type: GrantFiled: March 3, 2009Date of Patent: July 26, 2011Assignee: LG Chem, Ltd.Inventors: Sang-Choll Han, Jung-Min Ko, Seung-Tae Oh, Yune-Hyoun Kim, Byung-Su Park

Publication number: 20090155401Abstract: The present invention relates to a method of forming a nanopattern, and, more particularly, to a method of continuously forming a nanopattern in a large area and a method of forming a nanopattern on a substrate having a roll shape, and a substrate having a pattern formed using the method. A method of relatively moving a specimen having a large area and a light source of interfering light and a method of performing exposure through the relative axial movement of the light source of interfering light and the substrate having a roll shape while the substrate having a roll shape rotates are used to avoid the problems occurring in the related art, such as a large space required for the equipment during the formation of nanopatterns, a limited output of a laser, and a limited degree of freedom in patterns.Type: ApplicationFiled: March 27, 2007Publication date: June 18, 2009Inventors: Sang-Choll Han, Seung-Tae Oh, Deok-Joo Kim, Matthias Henyk
