Since the discovery of the carbon nanotube (CNT) 20 years ago, extensive effort has been made to utilize their exceptional intrinsic properties toward industrial applications. However, availability has significantly thwarted these endeavors. In this presentation, I will describe our efforts toward the economical mass-production of single-walled carbon nanotubes (SWCNT) based on the water-assisted chemical vapor deposition technique, from which highly efficient synthesis of vertically aligned SWCNTs grow from substrates (“SWCNT forests”). Further, I will discuss our work to promote the industrial use of SWCNTs as a member of the “Technology Research Association for Single-Walled Carbon Nanotubes” (TASC). This consortium of five companies and AIST was founded for the specific purpose of developing SWCNT technology. Specifically, I will present our progress on developing the technology for the synthetic control of SWCNTs and the development of standardized evaluation techniques for the purpose of understanding the relationship between the SWCNT forest structure, e.g. length, density, crystallinity, etc and the targeted property, e.g. conductivity, mechanical reinforcement, etc. Therefore, we have named this project the “World of CNT Forests.”
