Summary Polyaniline (PANI) was synthesized by oxidative polymerization method using potassium dichromate (K 2 Cr 2 O 7 ) as an oxidising agent. X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT‐IR) results confirm the emerlandine salt formation of PANI. Polystyrene and PANI based composites were prepared by solution cast method. Ultraviolet‐visible spectrophotometry (UV‐Vis) results of polymer composite film in the range of 200–400 nm indicate the interaction between neighbouring phenyl groups. Structural properties of the composite films were determined by the Fourier transform infrared spectroscopy (FT‐IR) and X‐ray diffraction (XRD). Morphological changes of PS‐PANI film were investigated by scanning electron microscopy (SEM) and optical micrographs.
