Abstract

Polyaniline nanofibers (PAni-NFs) have been synthesised under various concentrations (0.12, 0.16, and 0.2 g/L) of aniline and different times (2h and 3 h) by hydrothermal method at 90°C. Was conducted with the use of X-ray diffraction (XRD), Fourier Transform Infrared spectra (FTIR), Ultraviolet-Visible (UV-VIS) absorption spectra, Thermogravimetric Analysis (TGA), and Field Emission-Scanning Electron Microscopy (FE-SEM). The X-ray diffraction patterns revealed the amorphous nature of all the produced samples. FE-SEM demonstrated that polyaniline has a nanofiber-like structure. The observed typical peaks of PAni were (1580, 1300-1240, and 821 cm-1), analysed by the chemical bonding of the formed PAni through FTIR spectroscopy. Also, tests indicated the promotion of the thermal stability of polyaniline nanocomposite at temperatures above 600°C. Still, the PAni-0.12 g/L sample was better than the other samples, and the optical parameters manifested a decrease in the band gap (Eg) band gap. The observed TGA test findings also promoted polyaniline's thermal stability at temperatures reaching 600°C.
