In situ synthesized low-doped polyaniline/WS2 nanocomposites for charge storage applications: structural, morphological, electrical, and dielectric modulus analysis
Polyaniline (PANI) was synthesized via in situ polymerization route, and nanocomposites were prepared by incorporating tungsten sulfides (WS2) nanoparticles at varying concentrations (1 wt%, 2 wt%, and 5 wt%), to enhance their charge storage capabilities. Structural and morphological characteristics were investigated using XRD, FE-SEM, FTIR, TGA, BET, I–V measurements, and dielectric analysis. XRD confirmed the polycrystalline nature of all the nanocomposites, while FE-SEM supported by BET, revealed porous and interconnected morphological texture, beneficial for an effective charge transport mechanism. FTIR spectra showed prominent C = C and C = N stretching vibrations associated with the benzenoid and quinoid rings, indicating strong interfacial interactions between PANI and WS2 nanoparticles. TGA results demonstrated enhanced thermal stability in all nanocomposites compared to pure PANI. Dielectric measurements (20 Hz–1 MHz) revealed significant enhancement in permittivity for all nanocomposites, followed by frequency-dependent decline consistent well with Maxwell–Wagner interfacial polarization. I–V characteristics further confirmed the ohmic behavior of the samples. Overall, the enhanced dielectric response and superior thermal stability highlight the suitability of PANI/WS2 nanocomposites for high-performance charge storage and related electronic applications.
