Comparative studies on dispersing of multi-wall carbon nanotubes (CNTs) using two anionic surfactants (sodium dodecyl sulphate, SDS, and sodium dodecyl benzenosulfonate, SDBS) are presented. The studies were conducted on the surfactant concentrations that were close to the critical micelle concentration (CMC). The stability of CNTs suspensions obtained for surfactant solutions at concentrations lower than the CMC was investigated. It was also found that the surfactant structure has an influence on the diameter distribution of dispersed CNTs.
本文介绍了两种阴离子表面活性剂（十二烷基硫酸钠 SDS 和十二烷基苯磺酸钠 SDBS）在分散多壁碳纳米管（CNTs）方面的比较研究。研究在接近临界胶束浓度（CMC）的表面活性剂浓度下进行。考察了低于 CMC 浓度的表面活性剂溶液中 CNTs 悬浮液的稳定性。研究还发现，表面活性剂结构对分散 CNTs 的直径分布有影响。
