Abstract

A lube oil composition is provided. The lube oil composition includes a base oil and a carbon nanocapsule grafting with an alkyl group dispersed in the base oil, wherein the carbon nanocapsule is hollow or filled with metal, metal alloy, metal oxide, metal carbide, metal sulfide, metal nitride or metal boride.

Claims

1. A lube oil composition, comprising:

a base oil; and

a carbon nanocapsule grafting with an alkyl group dispersed in the base oil.

2. The lube oil composition as claimed in claim 1, wherein the carbon nanocapsule is covalently grafted with the alkyl group.

3. The lube oil composition as claimed in claim 1, wherein the alkyl group has a carbon number of 12-18.

4. The lube oil composition as claimed in claim 1, wherein the carbon nanocapsule is hollow.

5. The lube oil composition as claimed in claim 1, wherein the carbon nanocapsule is filled with metal, metal alloy, metal oxide, metal carbide, metal sulfide, metal nitride or metal boride.

6. The lube oil composition as claimed in claim 1, wherein the carbon nanocapsule is doped with nitrogen, phosphorous or boron.

7. The lube oil composition as claimed in claim 1, wherein the carbon nanocapsule has a diameter of 3-100 nm.
