METHOD FOR FABRICATING A THREE-DIMENSIONAL ULTRAFINE POLYMER CONDUCTING WIRE, OMNIDIRECTIONAL WIRING, AND ULTRAFINE POLYMER CONDUCTING WIRE FABRICATED USING THE METHOD

摘要

Disclosed is a method for fabricating a three-dimensional ultrafine polymer conducting wire having a high aspect ratio using a micropipette local chemical polymerization method. The fabricating method includes: (a) disposing the lower end of a micropipette, filled with an aqueous monomer solution for a conducting polymer, on a surface of a substrate at an alignment position for an ultrafine polymer conducting wire; (b) bringing the lower end of a micropipette into contact with the alignment position; (c) forming a meniscus of the aqueous monomer solution between the lower end of the micropipette and the surface of the substrate by spacing the micropipette apart from the surface of the substrate by a predetermined distance; and (d) moving the micropipette in a predetermined direction at a constant speed such that the meniscus reacts with the oxygen in the air to undergo polymerization and grow in the predetermined direction so as to become an ultrafine polymer conducting wire having a high aspect ratio.
