双壁碳纳米管研究进展

单壁碳纳米管和多壁碳纳米管的合成和应用研究得到广泛的关注和重视，并已取得了许多令人鼓舞的成果。双壁碳纳米管(DWCNTs)作为介于单壁碳纳米管和多壁碳纳米管之间的一种特殊结构碳纳米管，由于潜在的应用价值及作为研究碳纳米管层间作用最简单和理想的模型开始得到高度重视。介绍了双壁碳纳米管合成方法及理论和应用研究取得的进展。

Progress in Investigation of Double-wall Carbon Nanotubes

Synthesis and application investigation of carbon nanotubes (CNTs) has attracted considerable attention from scientists and businesses and great progress has been made. Because of its potential applications and its role as an ideal model for investigating interaction and coupling behavior between different layers, Double-wall carbon nanotubes (DWCNTs), as a special type between single-wall carbon nanotubes (SWCNTs) and multiwall carbon nanotubes (MWCNTs), are very important for theoretical and experimental researches. The paper reviews processes of synthesizing DWCNTs and progress made in investigation of DWCNTs.
