Surface Modification of Carbon Nanofiber with C₂₀H₃₈O₁₁ Polymer by Spun Calcination Method

Spun calcination introduces a novel approach for the development of materials suitable for optoelectronic applications, particularly carbon-based materials. In this study, we utilized the spun calcination technique to design rGO and rGO@CNF nanocomposites with the help of C20H38O11. By subjecting polymeric nanofibers to thermal reduction, we successfully achieved the formation of rGO and rGO@CNF, as confirmed by peak resolution in X-Ray diffraction analysis. The nanocomposites exhibited a crystalline phase, with average crystallite sizes of approximately 1.33 nm and 1.22 nm for rGO and rGO@CNF, respectively. The Raman spectroscopy shows intense G and D-bands observed in the spectra further supported the formation of these carbon-based materials, with IG/ID intensity ratios of approximately 0.85 and 0.87 for rGO and rGO@CNF, respectively. The photoluminescence study shows the structural growth of the nanocomposite indicated the diffusion of carbon surfaces, which revealed that both rGO and rGO@CNF shows lower electron-hole pair recombination rate. Consequently, these materials exhibited a considerable number of delocalized free electrons, leading to enhanced photoluminescence activity.
