This invention relates to homogeneously doped conductive polymer and a polymer blend thereof, wherein the dopant is a protonic acid having long carbon chain or larger substituent group. The resulting doped conductive polymer solution and polymer blend solution thereof can be cast to form free-standing films with metallic luster, of which the conductivities remain stable in the ambient condition and are in the range of 10-6 to 10-1 S/cm. The conductive polymer film and the conductive polymer composite film so prepared can be utilized in the anti-static wrapping materials for electronic components, and in electromagnetic interference shielding. |
