horizontal Carbon Nanotube alignment
Nanoscale, 2016Co-Authors: Matthew T Cole, William I. Milne, Vito CientanniAbstract:The production of horizontally aligned Carbon Nanotubes offers a rapid means of realizing a myriad of self-assembled near-atom-scale technologies – from novel photonic crystals to nanoscale transistors. The ability to reproducibly align anisotropic nanostructures has huge technological value. Here we review the present state-of-the-art in horizontal Carbon Nanotube alignment. For both in and ex situ approaches, we quantitatively assess the reported linear packing densities alongside the degree of alignment possible for each of these core methodologies.

Applied Physics Letters, 2010Co-Authors: Chi Li, David Hasko, Mark Mann, Didier Pribat, Baoping Wang, Gehan A. J. Amaratunga, Daping Chu, Wei Lei, Yan Zhang, William I. MilneAbstract:A vertically aligned Carbon Nanotube mesh emitter array has been fabricated and tested, giving a current density of up to 1.5 A / cm 2 , and a threshold field of 1.5 V / μ m for a current density 1 mA / cm 2 . Low temperature Carbon Nanotube growth is used to fabricate the Carbon Nanotube mesh emitter arrays significantly reducing the cost of the fabrication of large area electron emitters. This system exhibits ultralong lifetime.

Superhydrophobic Carbon Nanotube Forests
Nano Letters, 2003Co-Authors: Kenneth K. S. Lau, José Bico, William I. Milne, Gehan A. J. Amaratunga, Manish Chhowalla, Gareth H. Mckinley, Kenneth B. K. Teo, Karen K. GleasonAbstract:The present study demonstrates the creation of a stable, superhydrophobic surface using the nanoscale roughness inherent in a vertically aligned Carbon Nanotube forest together with a thin, conformal hydrophobic poly(tetrafluoroethylene) (PTFE) coating on the surface of the Nanotubes. Superhydrophobicity is achieved down to the microscopic level where essentially spherical, micrometer-sized water droplets can be suspended on top of the Nanotube forest.

Flexible, stretchable, transparent Carbon Nanotube thin film loudspeakers
Nano Letters, 2008Co-Authors: Lin Xiao, Zai Qiao Bai, Yuying Zhang, Li Qian, Qunqing Li, Liang Liu, Chen Feng, Zhuo Chen, Kaili JiangAbstract:We found that very thin Carbon Nanotube films, once fed by sound frequency electric currents, could emit loud sounds. This phenomenon could be attributed to a thermoacoustic effect. The ultra small heat capacity per unit area of Carbon Nanotube thin films leads to a wide frequency response range and a high sound pressure level. On the basis of this finding, we made practical Carbon Nanotube thin film loudspeakers, which possess the merits of nanometer thickness and are transparent, flexible, stretchable, and magnet-free. Such a single-element thin film loudspeaker can be tailored into any shape and size, freestanding or on any insulating surfaces, which could open up new applications of and approaches to manufacturing loudspeakers and other acoustic devices.

yarn spun from Carbon Nanotube forests production structure properties and applications
Particuology, 2013Co-Authors: Menghe MiaoAbstract:The discovery of drawable Carbon Nanotube forests opened up the possibility of constructing a wide range of pure Carbon Nanotube macrostructures and sparked interests in developing applications from these structures, especially pure Carbon Nanotube yarns. This review examines the various facets of the drawable Carbon Nanotube forests, synthesis and drawability, and their resulting yarns, structure, production, properties and applications. The structure, formation and properties of Carbon Nanotube yarns are compared with those of conventional textile yarns in order to obtain a better understanding of the science, structural mechanics and processing technology involved in Carbon Nanotube yarns.

electrical conductivity of pure Carbon Nanotube yarns
Carbon, 2011Co-Authors: Menghe MiaoAbstract:The porosity of multi-walled Carbon Nanotube yarns can be varied over a wide range by adjusting the yarn construction, resulting in a dramatic change in yarn electrical conductivity. When the yarn electrical conductivity is converted into specific conductivity, its value remains approximately constant irrespective of the changes in yarn construction and porosity. The process of Carbon Nanotube yarn production involves two key steps, the formation of a network of Carbon Nanotube bundles spliced together by the entanglement of individual Nanotubes and the compaction of the network into a cylindrical yarn. The splices formed from entangled individual Nanotubes play a much greater role in electrical conduction than the cross-over contact formed between CNT bundles by compaction during spinning.
