比较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））对多壁碳纳米管（CNTs）的分散效果。对接近临界胶束浓度（CMC）的表面活性剂浓度进行研究。研究了在低于CMC的浓度下获得的表面活性剂溶液的CNT悬浮液的稳定性。研究还发现，表面活性剂的结构对分散的碳纳米管的直径分布有影响。(c)2010年爱思唯尔公司All rights reserved.
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. (c) 2010 Elsevier Inc. All rights reserved.
