As shown in the article by Iijima et al. ( pp. 2332‐2334 ), for the use in fiber spinning the morphology of a rapidly grown Vertically Aligned Carbon‐Nanotube Forest (VACNF) can be controlled by a very simple and easy way which does not include traces of a polymer. The majority of as‐grown VACNFs consists of 2 to 5 walls with a mean tube diameter of 5‐7 nm based on TEM characterization. In the case of a spinnable VACNF, most of the carbon nanotubes (CNTs) are straight and well aligned but few CNT bundles consist of 8‐10 CNTs which are not aligned vertically. These bundles get shared by an adjacent thicker CNT bundle ‐ which is a very important step for understanding continuous fiber spinning.
