We show that the scale parameter of the distribution, which equals the mean of the natural logarithm of the ...
Debundling of singlewalled carbon nanotubes (SWNTs) has been mostly limited to liquidphase exfoliation. Since the SWNTs in dispersion are prone to aggregate and precipitate gradually during their storage, a solidphase method that provides debundled SWNTs as "stock solid" is highly required. Herein, we report on a solution to this issue, which is based on solidphase ball milling.
