Abstract

An emulsifier containing a modified graphite oxide material, which is a thermally exfoliated graphite oxide with a surface area of from about 300 m 2 /g to 2600 m 2 /g.

Claims (25)

1. An emulsifier, comprising a modified graphite oxide material, comprising thermally exfoliated graphite oxide having a surface area of from about 300 m 2 /g to 2600 m 2 /g.

2. The emulsifier of claim 1 , wherein the thermally exfoliated graphite oxide has a surface area of from about 400 m 2 /g to 2600 m 2 /g.

3. The emulsifier of claim 1 , wherein the thermally exfoliated graphite oxide has a surface area of from about 500 m 2 /g to 2600 m 2 /g.

4. The emulsifier of claim 1 , wherein the thermally exfoliated graphite oxide has a surface area of from about 300 m 2 /g to 1100 m 2 /g.

5. The emulsifier of claim 1 , wherein the thermally exfoliated graphite oxide has a bulk density of from about 40 kg/m 3 to 0.1 kg/m 3 .

6. The emulsifier of claim 1 , wherein the thermally exfoliated graphite oxide has a C/O ratio of from about 60/40 to 95/5.

7. The emulsifier of claim 1 wherein the thermally exfoliated graphite oxide has a C/O ratio of from about 65/35 to 85/15.

8. An emulsion, comprising thermally exfoliated graphite oxide having a surface area of from about 300 m 2 /g to 2600 m 2 /g, and at least one oil.

9. The emulsion of claim 8 , wherein the thermally exfoliated graphite oxide has a surface area of from about 400 m 2 /g to 2600 m 2 /g.

10. The emulsion of claim 8 , wherein the thermally exfoliated graphite oxide has a surface area of from about 500 m 2 /g to 2600 m 2 /g.

11. The emulsion of claim 8 , wherein the thermally exfoliated graphite oxide has a surface area of from about 300 m 2 /g to 1100 m 2 /g.

12. The emulsion of claim 8 , wherein the thermally exfoliated graphite oxide has a bulk density of from about 40 kg/m 3 to 0.1 kg/m 3 .

13. The emulsion of claim 8 , wherein the thermally exfoliated graphite oxide has a C/O ratio of from about 60/40 to 95/5.

14. The emulsion of claim 8 , wherein the thermally exfoliated graphite oxide has a C/O ratio of from about 65/35 to 85/15.

15. The emulsion of claim 8 , wherein the oil is selected from one or more of group consisting of alkanes, aromatic hydrocarbons, chlorinated hydrocarbons, silicon fluids, fatty acids, fatty acid esters, and heterocyclics.

16. The emulsion of claim 8 , wherein the oil is a least one petroleum distillate.

17. The emulsion of claim 8 , wherein the petroleum distillate is C4-C8 light hydrocarbons and/or C18-C40 hydrocarbons.

18. The emulsion of claim 8 , wherein the oil is at least one natural oil.

19. The emulsion of claim 18 , wherein the oil is one or more oils selected from the group consisting of corn oil, safflower oil, linseed oil, olive oil, and grape seed oil.

20. The emulsion of claim 8 , wherein the oil is crude oil.

21. The emulsion of claim 8 , wherein the oil is derived from tar sands.

22. The emulsion of claim 8 , wherein the oil is at least one tar and/or at least one asphaltene.

23. The emulsion of claim 8 , in the form of a paving compound or sealing compound.

24. The emulsion of claim 8 , in the form of a drilling fluid.

25. The emulsion of claim 24 , wherein the oil is crude oil.
