Nanoscale materials and nanocomposites composed of metals, conducting polymers, carbon nanotubes, because of their optical, mechanical, thermal, and chemical properties, are used in a huge number of applications. Current work includes the fabrication of PANI/rGO, as well as PANI/MWCNT nanocomposites and the study of their optical and thermal characteristics. The article describes in detail the methodology of synthesis and relative optical and thermal study of PANI/MWCNT and PANI/rGO nanocomposites with 8 wt. % rGO/MWCNT in pure PANI using an in-situ chemical oxidation polymerization process. Scanning electron microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopy were used to investigate the surface morphology of synthesized nanocomposites. Thermogravimetric analysis (TGA) was used to measure the thermal stability of PANI/rGO and PANI/MWCNT nanocomposites. UV-Visible spectrophotometry studies revealed a decrease in band gap values in specific PANI/rGO (8 wt. %) nanocomposite samples due to the enhanced significant interaction between rGO-doped PANI at molecular conjugation and the corresponding carbon allotropes. The study showed that PANI/rGO specimens have excellent structural, thermal, and optical characteristics, making them suitable for research and development in the field of energy storage devices and their applications.
