Sang-Uck Lee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9492866
    Abstract: The present invention relates to a belt-shaped metal nanostructure in which a wide surface area of catalytically active material can be realized even by a relatively small amount thereof so that it shows an excellent catalytic activity, and a method for preparing same.
    Type: Grant
    Filed: March 10, 2011
    Date of Patent: November 15, 2016
    Assignee: LG Chem, Ltd.
    Inventors: Won-Jong Kwon, Gyo-Hyun Hwang, Sang-Uck Lee, Hyuk Kim, Jung-Won Park, Sung-Ho Yoon, Kyung-Hoon Lee
  • Patent number: 8865251
    Abstract: The present invention relates to a metal nanobelt and a method of manufacturing the same, and a conductive ink composition and a conductive film including the same. The metal nanobelt can be easily manufactured at a normal temperature and pressure without requiring the application of high temperature and pressure, and also can be used to form a conductive film or conductive pattern that exhibits excellent conductivity if the conductive ink composition including the same is printed onto a substrate before a heat treatment or a drying process is carried out at low temperature. Therefore, the metal nanobelt and the conductive ink composition may be applied very appropriately for the formation of conductive patterns or conductive films for semiconductor devices, displays, solar cells in environments requiring low temperature heating. The metal nanobelt has a length of 500 nm or more, a length/width ratio of 10 or more, and a width/thickness ratio of 3 or more.

    Abstract: The present invention relates to a belt-shaped metal nanostructure in which a wide surface area of catalytically active material can be realized even by a relatively small amount thereof so that it shows an excellent catalytic activity, and a method for preparing same. The belt-shaped metal nanostructure comprises a metal nanobelt containing the first metal and a conductive polymer, in the shape of a belt having a nanoscale thickness, a width larger than the thickness and a length larger than the width; and the second metal coupled to one or both planes of the metal nanobelt defined by said width and length.
