Ppy-decorated graphene oxide: Synthesis and analysis of surface, structural and optical properties

Abstract

Here, we have syntheized Ppy (Polypyrrole) decorated GO (graphene oxide) and investigaed its morphological and optical characteristics. For fabrication of nanocomposites, in-situ polymerization technique was used. The crystalline size and strain of the synthesised sample were determined using an X-ray diffractometer (XRD). The surface morphology of the nanocomposites was investigated using field emission scanning electron microscopy (FESEM). The optical bandgap and PL spectra of the synthesised sample were examined using a photospectrometer and photoluminescence (PL) technique. The calculated crystalline size was ~ found as 5.91 nm with strain ~ 0.33907. In PL spectra, two peaks were found at ~ 430 nm and ~ 500 nm. The direct bandgap was calculated as~ 2.22 eV (visible region). Insights into their structural and optical characteristics are gained from the synthesis and characterization of PPy decorated GO nanocomposites, opening the door for further research and application in a variety of fields.
