A Study on the Influence of Different Anionic Surfactants on the AFM Scanning and Imaging of SWCNTs

This paper proposed a preprocessing method of SWCNTs dispersion based on rinsing technology. With the assistance of SDS, SC and SDBS, this method adopted the ultrasonication oscillation technology to solve the problem of SWCNTs dispersion. In addition, it compared the effect of the three kinds of surfactants on SWCNTs dispersion under the same conditions. And AFM was applied in this experiment to scan and image the samples. The results showed that the solubility and adsorption efficiency of the surfactants had influence on the SWCNTs dispersion quality. Furthermore, the paper primarily and theoretically modeled and analyzed the experiment results from the aspect of the surfactants' hydrophilic and lipophilic structure.
