Synthesis and X-ray diffraction study of polyaniline doped with chromium oxide

Polyaniline (PANI) and PANI / chromium oxide composites were synthesized by in situ chemical oxidative polymerization of aniline with CrO3 using ammonium peroxidisulphate as an oxidant. These composites were characterized by X-ray diffraction (XRD) and the results were compared with XRD of pure PANI and chromium oxide. The intensity of diffraction peaks of composites was lower than that for CrO3 and increases with increasing concentration of CrO3.Polyaniline (PANI) and PANI / chromium oxide composites were synthesized by in situ chemical oxidative polymerization of aniline with CrO3 using ammonium peroxidisulphate as an oxidant.

Synthesis and structural characterization of polyaniline/cobalt chloride composites

Polyaniline (PANI) and PANI /cobalt chloride composites were synthesized by in situ chemical oxidative polymerization of aniline with CoCl2.6H2O using ammonium peroxidisulphate as an oxidant. These composites were characterized by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The XRD study reveals that both PANI and composites are amorphous. The XRD and SEM results confirm the presence of cobalt chloride in the composites.

X-ray diffraction studies of polyaniline doped with Zn(NO3)2

Polyaniline (PANI) and PANI/zinc nitrate composites were synthesized by in situ chemical oxidative polymerization of aniline with Zn(NO3)2 using ammonium peroxidisulphate (APS) as an oxidant. These composites were characterized by X-ray diffraction (XRD) and the results were compared with pure Polyaniline and zinc nitrate.
