Abstract

A solvent-free composite powder comprising at least one thermoplastic material and at least one submicron nanoparticle material.

Claims (40)

1. A powder comprising:

homogenous composite particles;

said homogenous composite particles comprising at least one thermoplastic material and at least one submicron nanoparticle material;

wherein said at least one thermoplastic material comprises from about 50 to 99 weight percent of said powder;

wherein said at least one submicron nanoparticle material comprises from about 1 to 50 weight percent of said powder;

wherein said powder is solvent-free.

2. The powder of claim 1 , wherein said at least one thermoplastic material is a polymer, plastic, or wax, which can be melted and reformed.

3. The powder of claim 2 , wherein said at least one submicron nanoparticle material is a nano-aluminum oxide, nano-titanium oxide, or a nano-graphene oxide.

4. The powder of claim 1 , wherein said at least one submicron nanoparticle material has a mean particle size below 1,000 nm.

5. The powder of claim 1 , wherein said homogenous composite powder has a maximum particle size below 1,000 microns.

6. The powder of claim 1 , wherein said homogenous composite powder has a mean particle size ranging from 0.1 to 44 microns.

7. A composite powder comprising:

at least one thermoplastic material; and

at least one submicron nanoparticle material;

wherein said at least one submicron nanoparticle material is dispersed in said at least one thermoplastic material homogenously.

8. The composite powder of claim 7 , wherein said composite powder has a maximum particle size below 1,000 microns.

9. The composite powder of claim 7 , wherein said composite powder have a mean particle size ranging from 0.1 to 44 microns.

10. The composite powder of claim 7 , wherein said at least one submicron nanoparticle material has a mean particle size below 1,000 nm.

11. The composite powder of claim 7 , wherein said at least one thermoplastic material is a polymer, plastic, or wax, which can be melted and reformed.

12. The composite powder of claim 11 , wherein said at least one submicron nanoparticle material is a nano aluminum oxide.

13. The composite powder of claim 12 , wherein said composite powder is used as a coating additive to improve surface durability.

14. The composite powder of claim 7 , wherein said at least one submicron nanoparticle material is a nano titanium oxide.

15. The composite powder of claim 14 , wherein said composite powder is used as an additive in personal care products to improve SPF protection.

16. The composite powder of claim 7 , wherein said at least one submicron nanoparticle material is a graphene oxide.

17. The composite powder of claim 16 , wherein said composite powder is used as an additive to improve corrosion resistance in a surface coating.

18. The composite powder of claim 16 , wherein said composite powder is used as an additive to improve electrostatic dissipation in a surface coating.

19. A powder comprising:

homogenous composite particles;

said homogenous composite particles comprising at least one thermoplastic material and at least one submicron nanoparticle material;

wherein said at least one thermoplastic material comprises from about 50 to 99 weight percent of said powder;

wherein said at least one submicron nanoparticle material comprises from about 1 to 50 weight percent of said powder;

wherein said powder is produced by dry mixing, melting, cooling, pelletizing, and compressing said composite particles.

20. The powder of claim 19 , wherein said at least one thermoplastic material is a polymer, plastic, or wax, which can be melted and reformed.

21. The powder of claim 19 , wherein said at least one submicron nanoparticle material is a nano-aluminum oxide, nano-titanium oxide, or a nano-graphene oxide.

22. The powder of claim 19 , wherein said at least one submicron nanoparticle material has a mean particle size below 1,000 nm.

23. The powder of claim 19 , wherein said homogenous composite powder has a maximum particle size below 1,000 microns.

24. The powder of claim 19 , wherein said homogenous composite powder has a mean particle size ranging from 0.1 to 44 microns.

25. The powder of claim 1 , wherein said at least one submicron nanoparticle material has a mean particle size below 500 nm.

26. The powder of claim 7 , wherein said at least one submicron nanoparticle material has a mean particle size below 500 nm.

27. The powder of claim 19 , wherein said at least one submicron nanoparticle material has a mean particle size below 500 nm.
