Abstract: Provided is a method for producing a material that suppresses a decrease in the life of an insulation against surge voltage, that is, a material that provides a long dielectric breakdown lifetime. The method is a method for producing a fullerene-derivative-containing resin composition containing a fullerene derivative and a resin that has an affinity for a polar solvent, including: a step (I) of dispersing a fullerene derivative in a polar solvent; and a step (II) of mixing the polar solvent in which the fullerene derivative is dispersed with a resin that has an affinity for the polar solvent.

Abstract: A hydroxylated-fullerene-containing solution in which a hydroxylated fullerene is evenly nano-dispersed in a solvent removable at low temperature in a subsequent step is provided. The hydroxylated-fullerene-containing solution includes a continuous phase including a mixed solvent consisting essentially of tetrahydrofuran and water or including melted phenol, and at least one of a hydroxylated fullerene and a hydroxylated fullerene derivative that is dispersed as a dispersed phase in the continuous phase, wherein the number-standard average particle diameter of particles in the dispersed phase is 50 nm or less. This solution is applied onto a surface of a resin molding, and then tetrahydrofuran and water, as the mixed solvent, are removed to form a hydroxylated fullerene layer on the surface of the resin molding. Alternatively, this solution is mingled with a resin, and then the mixed solvent is removed to produce a hydroxylated-fullerene-containing resin composition.
