在目前的工作中，综述了使用多糖凝胶对单壁碳纳米管（SWCNT）进行金属（M）和半导体（S）分离。首先，介绍了M/S分离的进展，包括以下内容：使用琼脂糖凝胶电泳进行高产率分离的发现、无电场分离单壁碳纳米管（例如通过使用冷冻和挤压方法）、使用柱色谱连续分离的发展以及使用基于葡聚糖的凝胶的多柱对单壁碳纳米管的单手性分离。接下来，讨论了使用凝胶的分离机制，其中通过表面活性剂和凝胶的特定组合的凝胶选择性吸附S-SWCNT来实现分离。最后，讨论了单壁碳纳米管的分离以及分离后的单壁碳纳米管的使用的未来方向。（© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA，Weinheim）
In the present work, a review of the metallic (M) and semiconducting (S) separation of single‐wall carbon nanotubes (SWCNTs) using polysaccharide gels is presented. First, the progress of the M/S separation is described, including the following: the discovery of high‐yield separation using agarose gel electrophoresis, the separation of SWCNTs without an electric field, such as through the use of the freeze and squeeze method, the development of continuous separation using column chromatography, and the single‐chirality separation of SWCNTs using a multicolumn with dextran‐based gel. Next, the separation mechanism using gel is discussed, in which separation is achieved by selective adsorption of S‐SWCNTs by gel with a specific combination of surfactant and gel. Lastly, future directions for the separation of SWCNTs and for the use of the separated SWCNTs are discussed.(© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
