Assignee:

Hyperion Catalysis International, Inc. - Cambridge MA

International Classification:

D02G 300

US Classification:

428367

Abstract:

The invention relates to an interpenetrating network of carbon fibrils and a polymer, which comprises a rigidized, three-dimensional macroscopic assemblage of a multiplicity of randomly oriented carbon fibrils and an innerpenetrating mass of an organic polymer. The invention also relates to methods of making and using such innerpenetrating networks.

Filed:

Jun 6, 1995

Appl. No.:

8/466878

Inventors:

Howard G. Tennent - Kennett Square PA
James J. Barber - Arlington MA
Robert Hoch - Middle Village NY

Assignee:

Hyperion Catalysis International, Inc. - Cambridge MA

International Classification:

D01F 912

US Classification:

4234473

Abstract:

This invention concerns a discrete carbon fibril characterized by a substantially constant diameter between about 3. 5 and about 70 nanometers, length greater than about 5 times the diameter and less than about 100 times the diameter, an outer region of multiple essentially continuous layers of ordered carbon atoms and a distinct inner core region. The invention further concerns a plurality of such fibrils. The fibrils of this invention may be produced by contacting for an appropriate period of time and at a suitable pressure a suitable metal-containing particle with a suitable gaseous, carbon-containing compound, at a temperature between about 850. degree. C. and 1200. degree. C. , or by treating discrete carbon fibrils, characterized by a length greater than about 100 times the diameter. Carbon fibrils may also be continuously produced by continuously contacting for an appropriate period of time at suitable conditions.

B32B 900

US Classification:

4234473

Abstract:

The invention relates to carbon fibrils characterized by a substantially constant diameter, length greater than about 5 times the diameter, an ordered outer region of catalytically grown, multiple, substantially continuous layers of ordered carbon atoms having an outside diameter between about 3. 5 and 70 nanometers, and a distinct inner core region. Each of the layers and the core are disposed substantially concentrically about the cylindrical axis of the fibril. The fibrils are substantially free of pyrolytically deposited thermal carbon with the diameter of the fibrils being equal to the outside diameter of the ordered outer region.

International Classification:

C09C 1/60
C08K 9/02
C08K 3/04

Abstract:

Provided herein is a method of forming a composition by co-processing nanocarbon aggregates and carbon black aggregates, which includes providing nanocarbon aggregates, providing carbon black aggregates, and mixing the nanocarbon aggregates and the carbon black aggregates such that the nanocarbon aggregates disperse into looser aggregates of nanocarbons and carbon black, or individualized nanocarbons dispersed among the carbon black aggregates.
