The essential purpose of this KAKENHI budget (Grant-in-Aid for Research Activity Start-up) is to launch the research environment just after the adoption as a new faculty member by the university where the investigator is presently working at. Single-walled carbon nanotubes have been attracting much attention recently as a novel material. Single-walled carbon nanotubes are, however, usually in the form of bundled aggregates because of the remarkable van-der Waals attractive interaction between the adjacent tube walls. Such aggregated bundles are unsuitable for many applications. The purpose of the project is to experimentally explore and develop the way to resolve the aggregated bundles into mono-dispersed tubes. Thus far, with using a certain type of aromatic polymer, single-walled carbon nanotubes have been densely dispersed into an organic solvent, forming a high-density carbon nanotube "gels". Owing to this start-up budget the research environment has almost been established and the research is now at a stage where the further development is expected.

该KAKENHI预算（研究活动启动补助金）的基本目的是在研究人员目前工作的大学作为新的教职员工之后启动研究环境。单壁碳纳米管作为一种新型材料，近年来引起了人们的广泛关注。然而，单壁碳纳米管通常以束状聚集体的形式存在，因为相邻管壁之间存在显著的范德华吸引力相互作用。这种聚合束不适合于许多应用。本计画的目的是在实验上探索及发展将聚集束分解成单分散管的方法。到目前为止，通过使用某种芳香族聚合物，单壁碳纳米管已经密集地分散到有机溶剂中，形成高密度碳纳米管“凝胶”。由于有了这一启动预算，研究环境几乎已经建立起来，研究目前正处于预期进一步发展的阶段。
