CARBON NANOTUBE-POLY(X-4-STYRENESULPHONATE) COMPOSITE, AND A CARBON NANOTUBE-ELECTRICALLY CONDUCTIVE POLYMER COMPOSITE PRODUCED USING THE SAME

摘要

The present invention relates to a technique for making carbon nanotube-poly(X-4-styrenesulphonate) by using ionic bonding to introduce poly(X-4-styrenesulphonate) onto the surfaces of carbon nanotubes, and it relates to a method in which the carbon nanotube-poly(X-4-styrenesulphonate) is used as a dopant in the synthesis of an electrically conductive polymer in such a way as to finally produce a carbon nanotube-electrically conductive polymer composite which has outstanding dispersion properties. When producing a mixture of an electrically conductive polymer and carbon nanotubes, the technique of the present invention can be used in order to overcome the problem of phase separation between the electrically conductive polymer and the carbon nanotube components which is the greatest disadvantage exhibited by simple mixtures of the two components. Thus the present invention makes it possible to produce a composite in which an electrically conductive polymer has been synthesised on the surfaces of carbon nanotubes. Further, an advantageous effect can be obtained in that the composite has improved dispersion properties in solvents such as water.
