20150064426 | METHOD OF FORMING CONDUCTIVE FILMS WITH MICRO-WIRES - A pattern of conductive micro-wires as in a conductive pattern can be prepared using photo-lithography, or imprint technology. A photocurable composition is cured to form a pattern of photocured micro-channels. A conductive composition comprising metal nano-particles is added to the photocured micro-channels and excess conductive composition outside the photocured micro-channels is removed. The conductive composition in the photocured micro-channels is then dried at a temperature of less than 60° C. The dried conductive composition in the photocured micro-channels is treated with hydrogen chloride vapor to form conductive micro-wires in the photocured micro-channels at a temperature of less than 60° C. The outer surface of the conductive micro-wires is then polished in the presence of water, to form a micro-wire pattern. | 03-05-2015 |
