| Abstract: | Finely tuned: Carbon nanotubes are exposed to a CF4 radio‐frequency plasma (see picture). High‐resolution photoelectron spectroscopy shows that the treatment effectively grafts fluorine atoms onto the MWCNTs, altering the valence electronic states. Fluorine surface concentration can be tuned by varying the exposure time.  |
