![]() Random and aligned SWCNTs with a narrow range of chiralities are grown on substrates. To facilitate scaled-up SWCNT production and clarify the mechanism behind chirality selection, we show the synthesis of high melting point metal nanoparticles with near monodisperse sizes in the range of 1 to 5 nm using a continuous, gas-phase synthesis process. Recently, catalysts that remain solid state during growth have renewed the possibility to achieve chirality controlled through direct growth. However, direct growth of SWCNTs with a narrow chirality distribution is still challenging. Single-walled carbon nanotubes (SWCNTs) with controlled chirality possess superior performance in many sensor and electronic applications. I will then present our progress on the development of commercial applications, and finally I will present some or our work in developing the new technology for the synthetic control of SWCNTs. In one section of my presentation, I will describe our efforts toward the economical mass-production of single-walled carbon nanotubes (SWCNT). This presentation will provide an overview of our recent progress in the synthesis and application of highly efficient synthesis of millimeter-scale, vertically-aligned single-walled carbon nanotubes using the water-assisted “Super-growth” CVD. In this way, our center works to bring scientific discoveries and bring them to society. ![]() ![]() Over the past 15 years, our Center has been working in collaboration with academia and industry to support the establishment of a carbon nanotube industry in Japan by addressing the various stages of research spanning discovery, development, application, scale-up, and commercialization for the general top vital to the development of applications, such as synthesis, processing, and evaluation. This is precisely the work which is undertaken by the CNT-Application Research Center, AIST. However, to realize this vision, the practical developmental obstacles need to be resolved. In the nearly 30 years since the elucidation of the carbon nanotube structure, the reality of mainstream commercial applications, such as touch panels, sealing materials, high performance power sources, etc. ![]()
