Abstract:
1. A method of forming a negative pattern of carbon nanotubes which comprises the steps of: (a) providing surface-modified carbon nanotubes by introducing double bond-containing functional groups into the surface of the carbon nanotubes; (b) dispersing the surface-modified carbon nanotubes in an organic solvent along with a photoinitiator to obtain a liquid coating composition; (c) applying the liquid coating composition to a substrate and evaporating the organic solvent by prebaking to provide a coating film on the substrate; (d) exposing the coating film to UV light through a photomask having a desired pattern to induce photo-polymerization of the carbon nanotubes in the exposed areas of the coating film; and (e) developing the coating film with an organic developer to remove unexposed areas of the coating film and to obtain a negative pattern of the carbon nanotubes.
