Abstract

Compositions and methods of producing discrete nanotubes and nanoplates and a method for their production. The discrete nanotube/nanoplate compositions are useful in fabricated articles to provide superior mechanical and electrical performance. They are also useful as catalysts and catalyst supports for chemical reactions.

First claim

The invention claimed is:

1. A composition comprising:
inorganic plates with individual plate thickness of less than 10 nanometers;
wherein the inorganic plates are interspersed with carbon nanotubes consisting essentially of discrete exfoliated carbon nanotubes between the inorganic plates, the carbon nanotubes having a diameter ranging from about 1 nanometer to 150 nanometers, an oxidation level of from about 1 weight % to about 15 weight %, and the carbon nanotubes having an aspect ratio ranging from about 10 to 500, and wherein the inorganic plates are discernible graphene nanoplates.

2. The composition of claim 1 , wherein the inorganic plates and discrete tubes are present at a weight ratio of about 1:100 to 100:1.

3. The composition of claim 1 , further comprising a polymer selected from the group consisting of: thermoplastics, thermosets and elastomers.

4. The composition of claim 1 , further comprising inorganic materials selected from the group consisting of: ceramics, clays, silicates, metal complexes and salts.

5. The composition of claim 1 further comprising at least one electroactive material.

6. The composition of claim 1 further comprising at least one transition metal complex or active catalyst species.

7. The composition of claim 1 , wherein the carbon nanotubes have an aspect ratio ranging from about 25 to 500.

8. The composition of claim 7 , wherein the inorganic plates and discrete tubes are present at a weight ratio of about 1:100 to 100:1.

9. The composition of claim 7 , further comprising a polymer selected from the group consisting of: thermoplastics, thermosets and elastomers.

10. The composition of claim 1 , wherein the graphene nanoplates and carbon nanotubes are oxidized.
