Patent number: 7806974Abstract: A viscosity controllable highly conductive ink composition. The highly conductive ink composition comprises an organic solvent, nanoscale metal particles or metallo-organic decomposition compounds, and a thermally decomposable organic polymer. Specifically, since the thermally decomposable polymer can increase the viscosity of the highly conductive ink composition and be removed by subsequent thermal treatment, so as to decrease the impact on conductivity by organic polymer. Therefore, a viscosity-controllable conductive ink composition is obtained.Type: GrantFiled: May 24, 2006Date of Patent: October 5, 2010Assignee: Industrial Technology Research InstituteInventors: Gue-Wuu Hwang, Bao-Tsan Ko, Yi-Shin Lin

Patent number: 7632544Abstract: A nanopatterned template for use in manufacturing nanoscale objects. The nanopatterned template contains a nanoporous thin film with a periodically ordered porous geomorphology which is made from a process comprising the steps of: (a) using a block copolymerization process to prepare a block copolymer comprising first and second polymer blocks, the first and second polymer blocks being incompatible with each other; (b) forming a thin film under conditions such that the first polymer blocks form into a periodically ordered topology; and (c) selectively degrading the first polymer blocks to cause the thin film to become a nanoporous material with a periodically ordered porous geomorphology. In a preferred embodiment, the block copolymer is poly(styrene)-poly(L-lactide) (PS-PLLA) chiral block copolymer, the first polymer is poly(L-lactide), and the second polymer is polystyrene.Type: GrantFiled: May 18, 2004Date of Patent: December 15, 2009Assignee: Industrial Technology Research InstituteInventors: Rong-Ming Ho, Hui-Wen Fan, Wen-Hsien Tseng, Yeo-Wan Chiang, Chu-Chien Lin, Bao-Tsan Ko, Bor-Hunn Huang, Hsi-Hsin Shih, Joung-Yei Chen
