| Singlewalled and multiwalled carbon nanotubes (CNTs) have a high aspect ratio (1000 - 10000) with a length of typically a few micron. For many applications of carbon nanotubes, CNTs with length less than 1 micron are necessary to have rich chemistry, which can be used for promising one-dimensional building blocks in nanoscale. Previously strong acid treatments, ball milling, and sometimes mixing with polymers are used for an effective CNT cutting. Here we introduce high speed stirrer combined with sonication. Shortened carbon nanotubes are characterized using SEM, AFM, and dynamic light scattering. |
