SWCNTs were individually dispersed in ethylne glycol (EG) mild bath-type sonication using quaternized poly(furfuryl methacrylate)--(2-(dimethylamino)ethyl methacrylate) p(FMA--QDMAEMA) as a dispersing agent. QDMAEMA, which has alkyl groups, was more favorable to the dispersion ability of single walled carbon nanotubes (SWCNTs). The dispersion mechanism of SWCNTs in EG helical wrapping of polymer chains along their sidewalls was suggested based on transmission electron microscopic observation.
使用季铵化聚（甲基丙烯酸糠酯）-（甲基丙烯酸2-（二甲氨基）乙酯）p（FMA-QDMAEMA）作为分散剂，通过温和的浴式超声处理，将单壁碳纳米管（SWCNTs）单独分散在乙二醇（EG）中。具有烷基的QDMAEMA对单壁碳纳米管（SWCNTs）的分散能力更有利。基于透射电子显微镜观察，提出了SWCNTs在EG中聚合物链沿其侧壁螺旋缠绕的分散机制。
