A pH-responsive rigid surfactant derived from rosin was used to disperse and precipitate single-walled carbon nanotubes (SWNTs) in aqueous solution. The precipitated SWNTs could be re-dispersed by changing the pH without sonication owing to the hydrophobic steric layers formed by the rigid group and π-π interactions from the azobenzene group.
松香衍生的 pH 响应性刚性表面活性剂用于在水溶液中分散和沉淀单壁碳纳米管 (SWNTs)。由于刚性基团形成的疏水性位阻层和来自偶氮苯基团的 π-π 相互作用，沉淀的 SWNTs 可以在不超声的情况下通过改变 pH 值重新分散。
