Structure and Thermophysical Properties of Fullerene C60 Aqueous Solutions

The structure and thermophysical properties of fullerene C60 aqueous solutions were investigated both experimentally and theoretically. The aggregation kinetics results indicated that the structure of fullerene C60 aggregates in water could be described as a fractal system. The IR and electronic absorption spectra obtained confirm the presence of the crystalline phase in aqueous solution. The numerical values of thermodynamic coefficients :P, ;T, ;S, cP , and cV, and sound velocity were determined from the measured (P V T) data. The vibra- tional spectrum of the crystalline structure (Th symmetry group) formed from the hydrated single fullerene C60 molecules in aqueous solutions was calculated using the molecular dynamics approach.
