AbstractConducting polyaniline (PANI) nano particles doped with HCl was synthesized by a sonochemical method. Polyaniline/poly(styrene-alt-maleic acid)/polystyrene composites with different polyaniline content were developed by solution-dispersion blending method. The influence of poly(styrene-alt-maleic acid) concentration in composite structure was also investigated. The composite dispersed solution in tetrahydrofuran (THF) was cast to fabricate conductive films with evaporation of the

... . 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 composites was measured with four probe technique. All of obtained composites have conductivity and between them, the maximum electrical conductivity was 2.4 S/cm. The obtained composites were characterized by FT-IR and UV-Vis spectroscopy.
