Abstract

Methods of producing fullerenes in large-macroscopic quantities inexpensively is disclosed without using solid carbon material such as graphite. In a preferred embodiment, fullerenes are formed by a hot filament CVD procedure. The fullerenes occur in the soot that forms as a by-product on the edges of the substrate holder. Mass spectrum of soot deposits shows lines corresponding to C60. From the typical concentrations of gaseous species in the diamond-growing CVD chamber, hydrocarbon species including CH3 or C2H2 can be the precursors for the formation of fullerenes in the CVD chamber. A method of using fullerenes to enhance the properties of rubber composites is also described.
