Conducting blends of poly(diphenylamine) (PDPA) doped with H2SO4 or p-toluenesulphonic acid (TSA) and poly(vinylidene fluoride) (PVDF) were successfully prepared by using N,N′-dimethyl formamide (DMF) as solvent. Flexible, free-standing and conducting polyblends were obtained by solution casting which are characterized by electrical conductivity measurements, UV-Visible spectroscopy, FTIR spectroscopy, thermogravimetric analysis (TGA), differential scanning colorimetry (DSC), X-ray diffraction analysis, and cyclic voltammetry. The blends showed an increase in conductivity from about 10-9 to 10-5 S cm-1, with a percolation threshold of 5% of PDPA-H2SO4/TSA.
