  • The Controlled Pattern Growth of Aligned Carbon Nanotubes Abstract Micropatterns of aligned carbon nanotubes (CNTs) have been prepared by chemical vapor deposition (CVD) method, and patterned structure of aligned CNTs was controlled through patterned formation of silicon oxide (SiO2) using lithographic technology. The simultaneous growth of carbon nanotubes in different directions could be realized. The building of nanotube-based micro-pattern is useful for fabricating electrical devices. (请下载全文欣赏)

  • Self-Assembly of Large-Scale Micropatterns on Aligned Carbon Nanotube Films The fabrication of well-defined structures with nanoscale materials is a key technology,[1] and self-assembly is an efficient and often preferred process to build micro- and nanoparticles into ordered macroscopic structures.[2] As carbon nanotubes are attractive materials for nanotechnology because of their interesting physicochemical properties and molecular symmetries,[3–6] it is necessary to control the architecture of carbon nanotubes on the substrates. Most patterned carbon nanotubes are formed on prepatterned substrates or prepatterned catalysts during the fabrication process.[7–9] Herein we report the first use of a long-range force (capillary force) in the self-assembly of three-dimensional (3D) micropatterns on aligned carbon nanotube films through a water-spreading method after the growth of the carbon nanotube. It is considered that low-density regions or vacancies of carbon nanotube films play an important role in the formation of the pattern. Therefore different kinds of highly ordered micropatterned structures have been built in a controlled fashion by introducing vacancies artificially. (请下载全文欣赏)
