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.

Claims

1. A hydroxylated-fullerene-containing solution, comprising:

a continuous phase comprising (i) a mixed solvent consisting essentially of tetrahydrofuran and water, or (ii) melted phenol; and

at least one compound selected from the group of a hydroxylated fullerene and a hydroxylated fullerene derivative, 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.

2. The hydroxylated-fullerene-containing solution according to claim 1, wherein the solution comprises the mixed solvent, and contains water in a proportion of 15% by weight or more.

3. A method for producing a resin molding having a hydroxylated fullerene layer, in which at least a surface of the resin molding comprises a hydrophilic resin of a polymer having a hydrophilic group at a main chain or a side chain of the polymer, comprising:

applying, onto the surface of the resin molding, the hydroxylated-fullerene-containing solution as recited in claim 1, the solution comprising (i) the mixed solvent; and

removing tetrahydrofuran and water.

4. A method for producing a resin molding having a hydroxylated fullerene layer, in which at least a surface of the resin molding comprises a hydrophobic resin of a polymer being free from hydrophilic group at a main chain or a side chain of the polymer, comprising:

subjecting the surface of the resin molding to hydrophilizing treatment;

applying, onto the hydrophilized surface of the resin molding, the hydroxylated-fullerene-containing solution as recited in claim 1, the solution comprising (i) the mixed solvent; and

removing tetrahydrofuran and water.

5. A method for producing a hydroxylated-fullerene-containing resin composition, comprising:

mingling a resin with the hydroxylated-fullerene-containing solution as recited in claim 1, the solution comprising (i) the mixed solvent; and

removing tetrahydrofuran and water.

6. A resin molding produced by the method as recited in claim 3, wherein at least a surface of the resin molding comprises a hydrophilic resin, and a hydroxylated fullerene layer is formed on the surface of the resin molding.

7. A resin molding produced by the method as recited in claim 4, wherein at least a surface of the resin molding comprises a hydrophobic resin, and a hydroxylated fullerene layer is formed on the surface of the resin molding.

8. A hydroxylated-fullerene-containing resin composition produced by the method as recited in claim 5.
