报告摘要

Carbon nanotubes (CNTs) are one-dimensional tubular structure with excellent physichemical properties and of great potential for wide-range of applications. For example, single-wall carbon nanotubes (SWCNTs) can be either semiconducting or metallic, depending on their diameters and chiral angles. Semiconducting SWCNTs (s-SWCNTs) are ideal channel material for field effect transistors with advantages of high carrier mobility, high current on/off ratio, good stability and excellent flexibility; metallic SWCNTs can be used as interconnectors in circuits and network of transparent conductive films. Usually, as-prepared SWCNT samples are a mixture of s- and m-SWCNTs. To achieve their important application in electronics, it is essential to prepare pure s-/m-SWCNTs.

Based on the study of the growth mechanism of CNTs, we propose to prepare s-/m-SWCNTs by in situ growth selective etching and by catalyst design. Large-area s-/m-SWCNT films are obtained to fabricate high-performance transparant conductive films and thin film transistors. In addition, the property and application exploration of CNTs in lithium-ion batteries and electrocatalysis are also discussed.
