Abstract:
1. A method for producing a high density CNT film or pattern consisting of laminated CNT layers, wherein the layers are bound together by reaction of a carboxyl group and an amine group and wherein a top layer has exposed carboxyl groups on the surface thereof, and wherein the method for producing the CNT film or pattern comprises the steps of: (a) reacting a substrate having amine groups exposed on the surface or a substrate having amine groups exposed in a pattern with CNT having exposed carboxyl groups to form a CNT single layer or single layer pattern on the surface of the substrate by amidation reaction between the amine groups and the carboxyl groups; (b) reacting the CNT single layer or single layer pattern with an organic diamine to modify the CNT single layer with organic amine groups and reacting the organic amine groups with the CNT having exposed carboxyl groups to laminate a CNT layer thereon, wherein the CNT layer is laminated directly on the CNT single layer or single layer pattern by reaction of the amine groups and the carboxyl groups; and (c) repeating the step (b) to form laminated CNT layers, thereby forming a high density CNT film or pattern having exposed carboxyl groups.
