We investigated the effectiveness of electronic properties with single-walled carbon nanotube through spontaneous redox-reaction between the metal oxide ion such as MnO4- and carbon nanotube. The SWCNTs synthesized by the arc discharge method were used. The SWCNT powder was dispersed with sodium dodecyl sulfate (SDS) in deionized water and sonicated, followed by the centrifugation. The SWCNTs film has been fabricated by a filtration-wet transfer method on a various substrates such as glass, Si wafer, and polyethylene terephthalate (PET). The sheet resistance of SWCNTs film decorated with MnO2 has lower than that of as-prepared SWCNTs film.
