Single walled carbon nanotube (SWCNT) solution was prepared for the high transparent and conductive film. The optimum conditions such as the amount of surfactant, SWCNT, and binder were obtained by measuring the transmittance and electrical conductivity of the film. The values obtained were 0.005wt% (SWCNT), 0.035wt% (binder) and 0.1wt% (surfactant). The values of the transmittance and surface resistivity of poly(ethylene terephthalate) (PET) and polycarbonate (PC) films were 84.4%, 372 Ω/sq and 83.2%, 149 Ω/sq, respectively after electrostatic treatment of films. The adhesion test showed that the PET film has the strong interfacial interaction with SWCNT than PC. After bending test, no difference was observed in transmittance and electrical conductivity of both films. CNT solution with double walled carbon nanotube (DWCNT) was also prepared. However, the transmittance and surface resistivity of the film made by DWCNT solution showed lower and higher values than that made by SWCNT solution, respectively because of the impurities remained during manufacturing the DWCNT. After purification such as the heat and acid treatment, the impurities was still remained so that there is no significant effect on the transmittance and surface resistivity of the films.
