Breaking of multi-wall carbon nanotubes can be performed either by chemical or by mechanical forces. The chemically cut samples can be used for polymer fillers or reinforcing materials since they have reactive functional groups not only at the endings but also on the outer shells rendering to make chemical bond with the polymer matrix. Mechanical breaking of nanotubes results in material with small length/diameter ratio and quite homogeneous particle size distribution. This sample is recommended to use as adsorbent for various processes. It is assumed that the sample is not appropriate for use as polymer filler due to its characteristics.
