Patent ID: 6960425

Claim:
A method for forming a carbon nanotube pattern, comprising: (a) surface treating a substrate to expose amino groups thereon; (b) treating the surface-treated substrate with a linker of aminoalkylcarboxylic acid represented by the following formula 1: wherein R is a functional group capable of being dissociated by an acid, and n is an integer of 1 to 50, in the presence of a coupling agent to form amide bonds between the amino groups exposed on the substrate and the carboxyl groups of the aminoalkylcarboxylic acid; (c) applying a photo-acid generator onto the substrate, irradiating UV light to the substrate through a patterned photomask, and developing with an alkaline developer to form a positive pattern on which reactive amino groups are exposed; and (d) reacting the reactive amino groups on the substrate with carboxylated carbon nanotubes in the presence of a coupling agent to form a carbon nanotube layer.
