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)
