Abstract The presentthesis intends to investigate the dispersion behavior of graphitic –Carbon Nitride (g-C3N4) in different solvents. In this context, nineteen(19) different solvents were utilized covering a broad range of physical characteristics (e.g. polarity, boiling point etc.). Initially,the synthesizedg-C3N4was extensively characterized in powder form by Attenuated Total Reflectance (ATR-IR), Ultraviolet-visible (UV-vis) and Raman spectroscopy, as well as X-ray diffraction (XRD). Following the characterization of the material, dispersions were prepared through a tip-assistedultrasonicationprocess, followed by centrifugation. In thisway, stable dispersions were prepared since the supernatants were easily separated from the sediment. In addition, the final concentration of the dispersed and exfoliated g-C3N4flakes in each solvent was determined by the Beer-Lambert law. It should be highlighted, that this is the timethatstable g-C3N4dispersions were prepared invarious solvents bytip-ultrasonicationinstead of the conventional bath-assisted one. Finally, the Hansen Solubility Parameters (HSP) of the material were calculated
