Preparation of Conductive Nano composites based on Polyaniline / Poly (styrene -alt - maleic acid) blended with Polystyrene Sulfonic acid



Conducting polyaniline (PANI) nano particles were synthesized by a sonochemical method and doped with HCl. The series of composites based on Polyaniline-Poly(styrene-alt-maleic acid) blended with Polystyrene sulfonic acid with different component content ratios were prepared by solution-dispersion blending method. The influence of Poly(styrene-alt-maleic acid)(PSMAC) and polystyrene sulfonic acid (PSS) on composite properties were investigated. The composite dispersed solution in tetrahydrofurane (THF) cast to fabricate conductive films. 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 2.86 S/cm. The obtained composites characterized by FT-IR and UV-Vis spectroscopy.
