Cutting Single-Wall Carbon Nanotubes through Fluorination
Abstract
The fluorination of purified HiPco single-wall carbon nanotubes to a stoichiometry CF x ( x ⩽ 0.2) followed by pyrolysis of the partially fluorinated nanotubes up to 1000 °C was found to have “cut” the nanotubes to a range of short lengths (average <50 nm). The pyrolysis process was monitored in-situ with TGA-FTIR. The fluorine was driven off the nanotube structure in the form of COF 2 and CF 4 . The “cut” nanotubes have been characterized by Raman, ATR-IR, EDAX, and AFM measurements. Short bundles composed of strongly interacting individual nanotubes were found in the “cut” nanotube sample. The short lengths and specific reactivities should lead to novel applications for these nanotubes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
