Different polythiophene (PTh) nanostructures were prepared effectively via chemical oxidative polymerization in an aqueous media containing SDS as an anionic surfactant. The morphology of PTh was controlled by adjusting the concentrations of oxidant, reductant and surfactant, resulting in fibers, ribbons or spherical particles. The study examined the conductivity and structure of PTh and proposed a mechanism for transforming its morphology. The obtained powder characterization investigations were carried out by using FTIR to confirm the formation of the polymeric substance of PTh. The crystal structure of PTh is studied by XRD techniques. Based on the XRD experimentations, it has been confirmed that the PTh obtained is in amorphous form. The SEM and AFM of surface morphology and topography were also studied.
