F Functionalized Single Walled-Double Walled Carbon Nanotubes are produced by CCVD and is further purified or functionalized using a Dielectric Barrier Discharge process which provides greater control over the desired type & amount of Fluorine (a halogen) functionality which produces an exfoliated product that is much easier to disperse in the host matrix.
Fluorinated carbon nanotubes are known to be a good starting point for further sidewall derivatization of the sidewall with other molecules. These secondary reactions involving substituting the Fluorine atom from the sidewall have been utilized to produce C-N bond formation, free radical addition, and cycloaddition.
