Title:
METHOD FOR FORMING CARBON NANOTUBE FINE WIRING, FINE WIRING BOARD FORMED USING SAME, AND CARBON NANOTUBE DISPERSION SOLUTION FOR MANUFACTURING FINE WIRING
Document Type and Number:
WIPO Patent Application WO/2014/204042
Kind Code:
A1
Abstract:
The present invention relates to a method for forming carbon nanotube fine wiring and to a fine wiring board formed using same, the method comprising: a first step of preparing a dispersion solution comprising carbon nanotubes dispersed in a solvent; a second step of forming a droplet on a base material by using the dispersion solution; a third step of applying an electric field to the droplet by using two electrodes, and arranging the carbon nanotubes in multiple-strand form (rope-type); and a fourth step of evaporating the solvent of the dispersion solution contained in the droplet and thus forming linear carbon nanotube fine wiring. Also, the fine wiring board comprises the base material and carbon nanotube fine wiring comprising the carbon nanotubes of multiple-strand form which are located on the base material and have been arranged by the electric field. That is to say, when the wiring is arranged by the method of forming carbon nanotube fine wiring of the present invention, long wiring can be formed and simultaneously wiring having outstanding electrical conductivity can be formed, and the time taken to form the wiring can be shortened.
