摘要
以超声波为辅助工具,分别研究在水中加入不同类型的阳离子、阴离子型等表面活性剂对碳纳米管分散性的影响,通过记录分散的碳纳米管溶液的保存时间和离心时间现察其分散性,并采用SEM和TEM对分散效果进行分析和表征。研究结果表明,十六烷基三甲基溴化铵和乳化剂OP作为分散剂的分散效果最好。
With the superonic as a supplementary tool,the effects of cationic and anionic suffactants on the dispersion of carbon nanotubes were studied in the solvent of water, The preserved time of dispersed carbon nanotubes solution was determined. The dispersion of carbon nanotubes was observed by SEM and TEM. It＇ s found that the carboll nanotubes were dispersed very well in the cationic surfactant HTAB and emulsion OP with an approprizte concentration.
