Pure and different weight ratio of Cu-complex incorporated polypyrrole have been successfully prepared employing in situ polymerization of pyrrole solution with Cu-complex. The structure, morphology, optical and thermal characterization were carried out by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-Visible spectrophotometer (UV-Vis) and thermogravimetric analysis (TGA). The XRD results appear preparation amorphous polypyrrole and it amorphousity was reduced with doped Cu-complex. TEM images show preparing spherical nanoparticles of Cu-complex that covered rod morphology of polypyrrole and successfully process of in situ polymerization. on the other hand, the thermal stability of polypyrrole was increased with incorporation Cu-complex as demonstrated from TGA measurements. LCR measurements are appeared that the real and imaginary dielectric constant of hybrid nanocomposite is larger than pure polypyrrole and the storage charges increase with increasing the Cu-complex concentration.
