Research Abstract

A simple rubbing treatment was used to mechanochemically modify the surface of carbon fibers (CFs) and its effect on their surface structure and functional groups was studied. To control the mechanochemical effect, the shear forces accompanying rubbing were kept constant using newly designed friction type rubbing equipment. Scanning electron microscopy tests and the peak positions and widths of the main Raman spectroscopy bands indicated that there were no morphological changes to the CFs following rubbing. In contrast, X-ray photoelectron spectroscopy (XPS) showed an increase in oxygen-containing functional groups. The ratio of carboxyl groups on the CF surface increased with the shear force magnitude, indicating carbon surface oxidation. The difference between the Raman and XPS results indicates that modification was confined to the first few atomic layer. Additionally, shear stress inducing the mechanochemical reaction were quantitatively evaluated.
