Electrically conductive composite films from sulfonated poly(arylene ether sulfone) and polyaniline emeraldine base were prepared. The electrical conductivity values, which would be useful for a wide range of applications, were achieved after only 1 min of doping in protonic acid solution. A molecular interaction between the supportive matrix and conductive filler is inferred based on significant difference in the Fourier-transform infrared spectra of the doped and undoped composite films.
