Conducting polyaniline (PANI) nano particles doped with HCl were synthesized by a sonochemical method. Polyaniline/Poly (styrene- alt-maleic acid)/Polystyrene sulfonic acid nano composites with different polyaniline content were developed by solution-dispersion blending method. The influence of Poly (styrene-alt-maleic acid) (PSMAC) and polystyrene sulfonic acid (PSS) concentration in nano composite structure was investigated. The composite dispersed solution in tetrahydrofurane (THF) cast to fabricate conductive films with evaporation of the solvent. With only a mixing procedure and without any dispersant added, the PANI nanoparticles were well dispersed in the matrix polymer as indicated by scanning electron microscopy (SEM) images. The conductivity of obtained nano composites was measured with four probe technique. All of obtained nano composites have conductivity and between them, the maximum electrical conductivity was 3 S/cm. The obtained nano composites were characterized by FT-IR and UV-Vis spectroscopiess.
