In this study, the influence of anodic oxidation in different electrolyte systems on the wettability of carbon fibers was investigated. The surface properties of the anodized carbon fibers were studied through the measurement of XPS, SEM, and surface free energy analyses. It was shown that the surface functional groups containing oxygen on the anodized carbon fibers exert great effects on the surface energetics of fibers. Contact angle measurements based on the wicking rate of a test liquid showed that anodic oxidation lead to an increase in the surface free energy of the carbon fibers, mainly in its specific (or polar) component. In terms of surface energetics, it was found that anodic oxidation using acidic electrolyte improved the oxygen surface functional groups of carbon fiber surfaces. |
