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

摘要

Disclosed herein is a method for fabricating a three-dimensional ultrafine conducting polymer wire having a high aspect ratio by local chemical polymerization using a micropipette. The fabricating method includes the steps of: (a) disposing a lower end of the micropipette, filled with an aqueous monomer solution corresponding to a conducting polymer, over a surface of a substrate at an alignment point at which the ultrafine conducting polymer wire is to be formed; (b) bringing the lower end of the micropipette into contact with the surface of the substrate at the alignment point; (c) drawing the micropipette away from the surface of the substrate by a predetermined distance to form a meniscus of the aqueous monomer solution between the lower end of the micropipette and the surface of the substrate; and (d) moving the micropipette in a growth direction of the ultrafine conducting polymer wire at a constant speed such that the meniscus is grown into the ultrafine conducting polymer wire having a high aspect ratio by a polymerization reaction of the meniscus with oxygen in the air.
