PROCESS FOR PRODUCING PVP-FULLERENE COMPLEX AND AQUEOUS SOLUTION THEREOF

摘要

An aromatic hydrocarbon solution of a fullerene or a fullerene mixture is mixed with an ethanol solution of polyvinylpyrrolidone (PVP), water is added to the mixed solution, the solvent is removed and then an aqueous solution of a complex of a fullerene or a fullerene mixture with polyvinylpyrrolidone (PVP) is obtained. Under a condition free from a halogen, a PVP/fullerene complex excellent in manifestation of fullerene properties, stability and safety and an aqueous solution thereof are obtained.
