To Study the Structural Characterization of the Polyaniline/CoFe2O4 Nanocomposites

In the present research work, Polyaniline/CoFe2O4 nanocomposites were prepared using the co-precipitation method, which is economical and eco-friendly. The CoFe2O4 nanoparticles get adhered into a polymer using the in-situ chemical polymerization method. The various techniques were approached to characterize the prepared sample, such as XRD and FTIR. The peaks obtained at around 20.3 degrees and 25.2 degrees show the amorphous nature of PANI (low crystallinity). The appearance of characteristic diffraction peaks achieved at 35.5 degrees and 43.2 degrees ascribed to wellarranged crystalline cobalt ferrite pointing to the successive synthesis by co-precipitation route. Different analyses such as Debye- Scherrer, Halder, Wagner (H-W), and Williamson Hall (W-H) methods have investigated various parameters such as crystallite size and strain. The achieved values of crystallite size were highly correlated with Debye- Scherrer, Halder Wagner (H-W), and Williamson Hall (W-H) plots. The FTIR characterization confirmed the bonding among the Polyaniline/CoFe2O4 nanocomposites, which gets well-matched with XRD results.
