Surface modification of carbon nanofiber with high degree of graphitization

Article Abstract:

The platelet CNF which were first treated thermally, then mechanically and chemically to follow the morphological and structural change by TEM (transmission electron microscope), XRD (X-ray diffraction), and Raman spectroscopy are presented. This study also supports existence of the primary rodlike structural unit in carbon nanofibres.

Electrokinetics of carbon fibers produced by a direct oxyfluorination

Article Abstract:

Pan-based carbon fibers are treated by a direct oxyfluorination method to study the chemical surface composition and electrokinetic behavior of the fibers. The X-ray photoelectron spectroscopy (XPS) results show that carbon, fluorine, and oxygen are the main elements on the surface of oxyfluorinated carbon fiber specimens.

Characterization and modeling of the nonfaradaic response of ultrahigh surface area carbon fibers by electrochemical flow injection analysis

Article Abstract:

The experiment was conducted to study the ion partitioning properties of ultrahigh surface area carbon fibers (UHSACF's) using electrochemical flow injection analysis. The results provide a qualitative basis of understanding the ion flow into and out of the fractured carbon fibers.
