Topic of Research Seminar: A Detail Investigation Using Raman Spectroscopy to Obtain Quality Solvent Dispersion Via Sonication Processing of Graphene Nanoplatlets (GNPs)

Abstract: The work presented showcases comprehensive investigation into the quality solvent dispersion of graphene nanoplatelets (GNPs) achieved through sonication processing, utilizing Raman Spectroscopy for structural analysis. Key topics discussed include the structural quality analysis of GNPs, the effects of sonication parameters on these nanoplatelets, and the dispersion phenomena observed through Raman spectra. The relationship between exfoliation and sonication parameters is thoroughly examined, revealing critical insights into the optimal conditions for achieving high-quality dispersions. Additionally, this work delves into the quantification of disorder and defects within GNPs, providing a detailed understanding of how sonication influences the structural integrity of the nanoplatelets. The findings indicate that precise control over sonication parameters significantly impacts the exfoliation efficiency and the quality of GNP dispersions, as evidenced by the Raman spectral data. This research offers valuable guidelines for optimizing sonication processes to enhance the performance of GNP-based applications in various technological fields.
