In this work, we probed the effects of shear flow on the alignment of dispersed single-walled carbon nanotubes in polymer solutions. Two different systems were compared: Single-walled carbon nanotubes dispersed using an anionic surfactant and single-walled carbon nanotubes dispersed using an anionic surfactant and a weakly binding polymer. It was determined that the addition of the weakly binding polymer increased the degree of dispersion of the carbon nanotubes and the ability to induce their alignment when subjected to shear forces.
在这项工作中，我们探究了剪切流对聚合物溶液中分散的单壁碳纳米管排列的影响。比较了两种不同的体系：使用阴离子表面活性剂分散的单壁碳纳米管以及使用阴离子表面活性剂和弱结合聚合物分散的单壁碳纳米管。结果表明，添加弱结合聚合物提高了碳纳米管的分散程度以及在受到剪切力时诱导其排列的能力。
