Inside Back Cover: Morphology control of a rapidly grown vertically aligned carbon-nanotube forest for fi ber spinning (Phys. Status Solidi A 10/2011)
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.
