Embodiment 1

[0098] After mixing 3g of 3,4-ethylenedioxythiophene, 300g of 3wt% polystyrenesulfonic acid aqueous solution, 6g of sodium persulfate, 1g of ferric sulfate and 500ml of pure water, it was stirred for 3 hours. After adding 2 g of acrylic acid (AA) and 4 g of hydroxyethyl acrylate (HEA) to this reaction solution, it was heated and stirred for 3 hours.

[0099] After letting cool, remove residual ion in the solution with ion exchange resin, obtain dark blue 1.5wt% polystyrenesulfonic acid-poly(3,4-ethylenedioxy) thiophene and polyacrylic acid-polyhydroxyethyl acrylate aqueous solution (hereinafter referred to as: aqueous solution 1).

[0100] After mixing 1 g of aqueous solution 1 and 9 g of ethanol, mixed ethanol aqueous solution 1 was obtained. After coating the ethanol aqueous solution 1 on the polyester film and drying it in an oven at 120°C for 30 minutes, the conductive thin coating film was obtained. Table 1 shows the results of evaluating the resistivity of the conducti...
