Mechanochemical synthesis and properties of fullerene derivatives

A technique was developed of mechanochemical synthesis of the fullerene C₆₀ water-soluble derivatives. The derivatives obtained were characterized by elemental analysis, IR spectroscopy, and thermogravimetric analysis. The effect the substances obtained on the mechanical properties of the polyvinyl alcohol films was studied. A strengthening effect of fullerene derivatives on the elastic modulus, tensile strength, and tensile deformation of the polyvinyl alcohol films were found to become apparent already at the concentrations of 0.1–0.2 wt %.
