IMPROVED CATALYSTS FOR THE MANUFACTURE OF CARBON FIBRILS ANDMETHODS OF USE THEREOF

摘要

A method from the manufacture of a catalyst for the production of carbon fib rils comprising contacting a fibril-forming catalyst or precursors of a fibril-forming catalyst with an effective amount of a surfac tant and/or polyol. A catalyst for the production of car bon fibrils formed by contacting a fibril-forming catalyst or precursors of a fibril-for ming catalyst with an effective amount of a surfactant a nd/or polyol. Improved carbon fibrils or carbon fibril aggregates free of a continuous car bon thermal overcoat, with graphitic layers substantiall y parallel to the fibril axis, having a substantially constant diameter from about 1.0 to about 100 nanometers, and possessing enhanced dispers ion into other materials and enhanced electrical conductivity in those materials.
