The conductivity of pure PEDOT is less than that of polyaniline, but it can be much more significant when treated with organic solvents or aqueous solutions of the organic salts. Ont the other hand the conductivity of polyaniline also depends on the synthesis method, dopant, oxidizing agents etc.
Polyaniline is difficult to prepare in the form of thin films because of its brittle nature and the film conductivity is not uniform because of the formation of cracks and discontinuity.
