Abstract

The structure of transverse-layer carbon nanofibers as DNIPRO industrial carbon fabric produced by pyrolysis of hydrated cellulose is assessed and their oxidation temperature (Тox = = 923 ± 10K) is found. Fractionated extraction of carbon (as СО2) in a purified oxygen flow was monitored by coulometry of extracted СО2 versus time at Тоx. A selective chemical procedure for qualitative identification and determination of transverse-layer carbon nanofiber content of nanocarbon materials of arbitrary composition is developed.
