Poly (3-hydroxybutyrate-co- 3-hydroxyvalerate)(PHBV) and polyaniline (Pani) were mixed in different weight ratios i.e. 100:0, 0.05, 1.5, 2.5, 3.5 and 5 to produce composite films. Polyaniline (PANI) synthesized by emulsion polymerization technique using an aqueous solution of CSA, ammonium per sulfate and aniline monomer In order to evaluate the influence of Pani. CSA addition on the final Thermal, morphological, and topographic properties of PHBV. A complete microstructural, and thermal characterization of films of PHBV/Pani blends has been performed. The following characterization techniques were employed: Fourier transform infrared (FTIR) spectroscopy, thermo gravimetric analyses (TGA-DTA), scanning electron microscopy (SEM), simultaneous. It has been observed that the micro- structure of PHBV/Pani.CSA was remarkably affected by blending composition. In order to study the surface topography of the PHBV and its composition with Pani.CSA, the surface of the prepared films were explored by an atomic force microscope (AFM).
