摘要：

Single-walled carbon nanotubes functionalized by phenyl groups can be sulfortated in oleum (H2SO4, 20% free SO3) to give materials that exhibit high solubility in water as determined by centrifugation in conjunction with UV-vis-near-infrared measurements. Cryo-transmission electron microscopy images show that extensive debundling occurs during the sulfonation step.
