Scanning tunneling microscopy (STM) has been applied to the study of the topography of polyacrylonitrile (PAN)‐based carbon fibers before and after electrochemical surface treatments. The results show that the electrical anodic oxidation only changes the surface aspects; at nanometric resolution; the nanostructure and nanotexture such as the step‐like crystallite stacking are decreased with increasing electric current densities.
