Abstract

Provided is a resin composition having excellent heat resistance by virtue of improved compatibility of a fullerene with a resin. Specifically, provided is a long-chain alkyl-etherified fullerene derivative, including: a fullerene skeleton formed of a spherical shell-shaped carbon molecule; and a long-chain alkyl group having 4 or more carbon atoms, which is bonded to the fullerene skeleton through an ether bond.

Claims

1. A long-chain alkyl-etherified fullerene derivative, comprising:

a fullerene skeleton formed of a spherical shell-shaped carbon molecule; and

a long-chain alkyl group having 4 or more carbon atoms which is bonded to the fullerene skeleton through an ether bond.

2. The long-chain alkyl-etherified fullerene derivative according to claim 1, further comprising a hydroxy group which is bonded to the fullerene skeleton.

3. The long-chain alkyl-etherified fullerene derivative according to claim 2, wherein a ratio (y/z) of a number y of the long-chain alkyl groups to a number z of the hydroxy groups is from 1/1 to 9/1.

4. A production method for the long-chain alkyl-etherified fullerene derivative of claim 1, comprising:

synthesizing a polycyclosulfated fullerene from a fullerene and fuming sulfuric acid; and

synthesizing the long-chain alkyl-etherified fullerene derivative by introducing the long-chain alkyl group to the fullerene skeleton through the ether bond generated by reacting the polycyclosulfated fullerene with a long-chain alcohol.

5. A resin composition, comprising:

a resin; and

the long-chain alkyl-etherified fullerene derivative of claim 1.

6. The resin composition according to claim 5, wherein a content of the long-chain alkyl-etherified fullerene derivative is from 0.01 part by weight to 10 parts by weight with respect to 100 parts by weight of the resin.

7. The resin composition according to claim 5, wherein the resin comprises at least one resin selected from the group consisting of a crystalline thermoplastic resin, a non-crystalline thermoplastic resin, and a curable resin.
