Polypyrrole-Cu Nanocomposite was polymerized using un-Hydrus ferric chloride (Fe Cl3) as an oxidizing agentin a chemical oxidation method. PPy/Cu nanocomposite prepared with varying amounts of copper (0.5, 1, 5, 7, and10 wt. percent). The composition of nanocomposites was investigated using Fourier Transform Infrared (FTIR). FTIR results show peaks shifting towards higher wavenumbers than pure PPy, indicating better conjugation and chemical interaction between PPy and Cu particles. A.C conductivity behaviors of Polymer nanocomposites of various compositions were investigated at different frequencies (120 Hz–5 MHz), and it was found that at high-frequency, A.C conductivity for nanocomposites that contain 5,7,10% of Cu sharply increases with increasing frequency also, Ac conductivity increases with increasing concentrations of Cu in nanocomposites that can be attributed to the electronic polarization
