ABSTRACT:
Cylindrical carbon fibrils with a substantially const. diam. at 3.5-70 nm, substantially free of thermal overcoat, with length approx. 102-104 the diam., an outer region of multiple, essentially continuous layers of ordered C atoms, and a distinct inner core region, are produced by contacting C-contg. compds., e.g., arom., nonarom., and O-contg. hydrocarbons, with supported, catalytic, metal-contg. particles, in the presence of compds., e.g., CO2, H2, H2O, and CO, which react with C at 850-1200.degree.. The fibrils are (highly) useful in the manuf. of composites and are effective as reinforcing materials, elec. and thermal cond. enhancers, electromagnetic shielding materials, and in increasing the surfaces area of electrodes and electrolytic capacitor plates. Thus, in 23 expts., using Fe-based, supported catalysts and 9:1 H-benzene mixts., the effect of pretreatment, time, and temp. on the formation of fibrils is demonstrated.
