Publication number: 20140231723Abstract: A method of enhancing the conductivity of silver in a silver-containing film formed on a substrate is disclosed. A silver-containing film, including silver particles and a hydrophilic binder is produced. Thereafter, the method includes exposing the silver-containing film to hot water vapor so that the binder absorbs water; drying the silver-containing film to remove water in the binder, and repeating the hot water vapor and drying steps at least one additional time to enhance the conductivity of the silver.Type: ApplicationFiled: February 20, 2013Publication date: August 21, 2014Inventors: Kurt Michael Sanger, Charles Francis Scaglione

Patent number: 8808583Abstract: A method for manufacturing a conductive adhesive containing a one-dimensional (1D) conductive nanomaterial is revealed. The method produces a conductive adhesive by mixing the 1D conductive nanomaterial with water-based or solvent-based resin solution. The conductive adhesive has good industrial applications, not influenced by industrial adaptability and environmental adaptability. The conductive adhesive obtained also has better conductivity. Moreover, the amount of the 1D conductive nanomaterial used in the present invention is less than the amount of conductive nanoparticles used and the cost is reduced effectively.Type: GrantFiled: June 30, 2010Date of Patent: August 19, 2014Assignee: Chung Shan Institute of Science and Technology Armaments Bureau, M.N.D.Inventors: Yi-Hsiuan Yu, Bao-Yann Lin, Ming-Hsiung Wei, Lea-Hwung Leu, Gou-Hong Yiin, Chen-Chi M Ma
