摘要

The current investigation is the first effort to measure the magnetic characteristics of (CuO, ZnO and CuO-ZnO)/Polyaniline Composites. In this study, the elements of composites such as PANI, CuO and ZnO were synthesized chemically, whereas the composite was synthesized using ex-situ method. Fourier transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Vibrating Sample Magnetometer (VSM) and X-ray Diffraction (XRD) were employed to evaluate the as-prepared composites. Magnetic characteristics parameters such as magnetic saturation (Ms), magnetic remanence (Mr), and coercivity (Hc) were effectively determined using VSM data. Ms = 48.79 emu/g, Mr = 14.7 emu/g, and Hc = 0.38Oe are the highest values of all magnetic properties associated with the CuO-ZnO/Polyaniline composite. We observed that ZnO and CuO doping in PANI nanoparticles leads to enhancement in the magnetization that might be suitable for magnetic sensors, data storage, supercapacitors, spintronics devices.
