Selective Growth of CVD-based Carbon Nanotubes through the Nanostructured Control and Their Novel Multi-functions

碳纳米管（CNT）已被公认为推动绿色创新的关键材料，以产生广泛应用的新技术，例如新型半导体、先进复合材料、环境材料和可能的生物应用。本课题旨在探索一种精确控制双壁碳纳米管（DWNT）和多壁碳纳米管（MWNT）生长和结构的方法，揭示其生长机理，并选择性地生长所需的碳纳米管。目的是从材料科学的角度，通过精确控制微观结构和电子功能等，为基础科学，应用和理解CNT的基本毒性方面做出贡献。从安全纳米技术作为“安全创新”的观点来看，结构可控的碳纳米管应该是碳纳米管科学和技术有前途的增长点

Carbon nanotube(CNT) has been recognized as a key material that drives the green innovation to generate new technology in a wide range of applications such as novel semiconductor, advanced composites, environmental materials and possible bio-applications. Present project aims especially to exploit a way to precise control of the growth and structure of double-walled(DWNT), and multi-walled CNT(MWNT), to reveal their growth mechanism, and to selectively grow desired CNT. The goal is to contribute to basic science, applications and understanding the basic toxicity aspect of CNT, from viewpoint of materials science, through an exact control of such as the microscopic structure and the electronic function. From the viewpoint of safe-nanotechnology as" Safe Innovation", the structurally controlled CNT should be pursued for promising growth of CNT science and technology
