Embodiment 1

[0082] The aqueous solution of the polystyrene sulfonic acid-poly (3,4 ethylenedioxy) thiophene of 50g, the activated carbon fiber of 3g (wire diameter is 10nm, and surface area is 1200m 2 / g), 10g of ethanol and 3g of ethylene glycol were mixed and stirred to obtain a mixed solution 1 of activated carbon fiber and polystyrenesulfonic acid-poly(3,4-ethylenedioxy)thiophene. After coating the mixed solution on a polyester film and drying it in an oven at 120°C for 60 minutes, a thin conductive coating film was obtained. Table 1 shows the results of evaluating the resistivity of the conductive thin coating film.
