Assessing the Internal Structure of Cross-Linked Carbon Nanofibers by Chemical Methods
Powder Metallurgy and Metal Ceramics(2017)
Abstract
The structure of cross-linked carbon nanofibers of DNIPRO industrial carbon fabric produced by pyrolysis of hydrated cellulose is assessed, and their oxidation temperature (T ox = 923 ± 10 K) is found. Fractionated extraction of carbon (as CO 2 ) in a purified oxygen flow is measured by coulometry of the extracted CO 2 versus time at T ox . A selective chemical procedure for qualitative identification and determination of cross-linked carbon nanofibers in carbon nanomaterials of arbitrary composition is developed for the first time.
