摘要：

An easy and simple preparation method for individually dispersed single-walled carbon nanotubes (SWNTs) in both liquid and dried solid states was developed using triphenylene derivatives. Furthermore, highly concentrated solution of SWNTs (0.7-0.8%) was successfully prepared, and also the SWNTs were dispersed well after the addition of methanol (up to 70%) for a long time. These properties (redispersion ability and dispersion to organic solvent) were not observed in typical dispersing surfactants, such as sodium dodecylbenzensulfonate and sodium cholate. These unique features of the surfactant-stabilized SWNTs promised to be highly useful for practical applications of SWNTs. (c) 2009 The Japan Society of Applied Physics
