表面活性剂，分子表面活性剂，被广泛用于稳定单壁碳纳米管（SWCNT）和许多其他纳米材料在水中，以促进溶液处理和设备集成。然而，众所周知，当不再需要表面活性剂时，很难干净地去除它们。即使是高温热退火也会留下残留物，这些残留物会降低单壁碳纳米管的其他显著的电学和光学性质。此外，热退火会破坏较小直径的纳米管（
Surfactants, molecular surface-active agents, are widely used to stabilize single-walled carbon nanotubes (SWCNTs) and many other nanomaterials in water to facilitate solution processing and device integration. However, it is notoriously difficult to cleanly remove surfactants when they are no longer needed. Even high-temperature thermal annealing leaves residues that can degrade the otherwise remarkable electrical and optical properties of SWCNTs. Moreover, thermal annealing damages smaller-diameter nanotubes (
