| Abstract: | Electrochemical surface treatment of rayon based carbon fiber has been studied. The acidic functions generated by surface treatment were measured by NaOH uptake. The tensile strengths of carbon fibers which had been subjected to surface treatment were measured by tensile testing. The scanning electron microscope(SEM) showed us the surface morphology of carbon fibers. Based on methylene blue(MB) adsorption, we can calculate the fiber surface area. Wetting properties of carbon fiber were measured using a wicking method, and contact angles were calculated from the free energy values. The crystallite dimensions on the surface were measured by Raman spectroscopy. The ratio of the intensity of the 1355 cm -1 and 1575 cm -1 bands is proportional to the crystallite dimension on the surface. |
