| Abstract: | The surface of PAN-based carbon fiber was directly modified with fluorine-oxygen mixtures at room temperature. The surface
characteristics of the modified fiber were determined by using X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD),
and dynamic contact angle analyzer. The surface free energy was also calculated with the Owens-Wendt geometric mean method
using water and methylene iodide contact angle. The surface of carbon fiber was changed into hydrophilicity by the formation
of semicovalent C-F bond and C-O bond depending on reaction conditions and the surface free energy of oxyfluorinated fiber
was significantly increased. |
