✦ Synopsis
Amoco M40 PAN-based carbon Ðbers were electrochemically oxidized in a pilot plant system. The changes in the surface of the Ðbers were monitored using monochromatic x-ray photoelectron spectroscopy (XPS). A parallel experiment using achromatic x-radiation was conducted for comparison. Other graphitic materials were also studied. Decomposition of the Ðber due to x-ray exposure could be e †ectively eliminated by using the monochromator. The use of monochromatic x-radiation produced considerable narrowing in the linewidth of the graphitic peak. This allowed the curve Ðtting of the component peaks to be performed with signiÐcantly greater conÐdence.
