Carbonized Electrospun Nanofiber Sheets for Thermophones
ACS Applied Materials & Interfaces, 2016Thermoacoustic performance of thin freestanding sheets of carbonized poly(acrylonitrile) and polybenzimidazole nanofibers are studied as promising candidates for thermophones. We analyze thermodynamic properties of sheets using transport parameters of single nanofibers and their aligned and randomly electrospun thin film assemblies.

Reactivity of Carbon Nanofibers with Fluorine Gas
Chemistry of Materials, 2006The present study highlights the reactivity of carbon nanofibers (CNFs) with fluorine gas. Highly purified and graphitized CNFs were treated under a stream of fluorine gas for 16 h at temperatures ranging from 380 to 480 °C. Different fluorination temperature zones have been revealed by direct physicochemical analysis such as XRD, Raman spectroscopy ...

Chlorine Effect on the Formation of Carbon Nanofibers
Journal of Nanoscience and Nanotechnology, 2012Platelet graphite nanofibers (GNFs) and turbostratic carbon nanofibers (CNFs) are synthesized by the thermal evaporation and decomposition of a polymer-based mixture at 700 degrees C using Ni as a catalyst. The mixture consists of poly(ethylene glycol) (PEG), serving as the carbon source, and hydrochloric acid solution (HCl(aq)), serving as the ...
