Synthesis, characterization of Ag@PANI core-shell nanostructures using solid state polymerization method

Abstract

One-step reaction has been developed to obtain Ag@Polyanilin (Ag@PANI) core-shell nano-structures. Aniline sulphate was oxidized by silver nitrate using solid-state polymerization method at room temperature. The structure and morphology of the core-shell were characterized by the Fourier transform infrared (FTIR) spectra, Ultraviolet-Visible (UV–Vis) absorption spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The XRD patterns displayed both the broad amorphous polymeric and sharp metallic peaks. The results from TEM and SEM images showed that the nano-composites have coreshell structures. The changes occurring in the structure of PANI are discussed on the basis of infrared and UV-Vis spectroscopy. The spectra revealed the formation of the nano-composites.
