S. Kashimura et al., Surface oxidation and activation of carbon fiber using radical NO3 center dot generated by anodic oxidation of NO3-, ELECTROCH, 67(12), 1999, pp. 1117-1119
Introduction of hydroxyl group on the surface of carbon fiber was attained
by the indirect anodic oxidation of carbon fiber with NO3. generated by ano
dic oxidation of NO3-. This hydroxyl group was found to have enough chemica
l reactivity with electrophiles and the modification of carbon fiber surfac
e was attained by using the reactivity of the hydroxyl group.
