Conducting polymer nano wire by ultra-short pulses via an AFM cantilever and therof method

摘要

In the present invention, an electric field is formed only in a local region around an atomic force microscope (AFM) cantilever tip by using an ultrashort pulse voltage in polymerizing a conductive polymer, The present invention relates to a method of manufacturing conductive polymer nanowires using AFM cantilevers and ultra-short pulse voltages. The method for manufacturing a conductive polymer nanowire of the present invention includes: an AFM cantilever tip fixing step of fixing an AFM cantilever tip to an AFM liquid cell (AFM liquid cell) and connecting a wire to a spring for fixing the AFM cantilever tip; An ultrasound pulse voltage source connection step in which the anode of the ultrasmall pulse voltage source is connected to the wire connected to the gold surface of the AFM sample and the cathode is connected to the wire connected to the AFM cantilever tip; An aqueous solution injection step of injecting an aqueous solution containing 0.7 M pyrrole aqueous solution and 0.002 M aqueous sulfuric acid solution into an AFM liquid cell; Gold surface confirmation step to confirm that there is nothing on the gold surface by imaging with AFM; And a voltage applying step of applying an ultra-short pulse voltage while performing an image with the AFM cantilever tip.
