The mechanism of surfactant-assisted dispersion of single-walled carbon nanotubes in water is studied by small-angle neutron scattering. The previously hypothesized formation of cylindrical micelles with the nanotubes forming the core of cylinders is inconsistent with the data presented. The scattering data favor a random structureless adsorption model for the dispersion of the nanotubes.
通过小角中子散射研究了表面活性剂辅助单壁碳纳米管在水中分散的机理。先前假设形成以纳米管为圆柱核心的圆柱形胶束，这与所呈现的数据不一致。散射数据支持纳米管分散的无规无结构吸附模型。
