Method for synthesizing carbon materials from carbon agglomerates containing carbine/carbynoid chains

Abstract

Provided is a method for synthesizing carbon agglomerates containing metastable carbyne/carbynoid chains; a method for synthesizing carbon or carbon compound allotropes from the agglomerates containing metastable carbyne/carbynoid chains; and the uses of the methods. The method for synthesizing carbon agglomerates containing metastable carbyne/carbynoid chains includes the following steps: a) forming carbon vapor precursors, containing carbine/carbynoid chains, by decomposing a carbon gas selected from among CH4, C2H2, C2H4, gaseous toluene, and benzene in the form of vapors at a temperature T such that 1 500° C.<T≦3 000° C.; and b) condensing the carbon vapor precursors, obtained in Step a), on the surface of a substrate, the temperature Ts of which is less than the temperature T. The invention is particularly of use in the field of electronics.
