| Popis: | Polyaniline (PANI) coupled with Se0.95Fe0.05 in various weight percentage (5 and 10 wt%) were formed by in situ polymerization method of PANI in the presence of Se0.95Fe0.05. The functionality of the investigated nanocomposites was investigated by X-ray diffraction (XRD), Fourier transform infrared (FTIR), vibrating sample magnetometer (VSM), and photoluminescence (PL) analyses. The structural characteristics of PANI and the existence of Se0.95Fe0.05 together with PANI were confirmed using XRD. The different functional groups of nanocomposite were studied using FTIR. PANI/Se0.95Fe0.05 nanocomposites exhibited a weak ferromagnetic behavior. Law of Approach to saturation was used to determine the saturation magnetization of nanocomposites samples. The PL of PANI and nanocomposites emitted five emissions in violet and blue ranges. The PL intensity of the emission peaks is significantly reduced when Se0.95Fe0.05 is introduced to PANI matrix. |
