Abstract
We investigated the hydrophilicity of fluorinated carbon fibers at room temperature, that is a new method of surface treatment, and found that through this treatment, wettabillity of the surface of carbon fibers increased dramatically without decrease of tensile strength. Observation by scanning electron microscope (SEM) showed the same surface morphology of fluorinated carbon fibers as that of original fiber. On the other hand, of anodic oxidated fibers. In the case of anodic oxidation as the wettabillity of oxidated fibers increased, the surface roughness increased and resulted in the decrease of tensile strength.
