Abstract

A new type of “smart” single-walled carbon nanotubes is created by wrapping a pyrene-labeled CO2-responsive polymer via π–π stacking. The polymer/SWNT hybrids not only undergo a hydrophobic–hydrophilic transition upon CO2 stimulus of CO2 in a mixed solvent, but also exhibit switchable dispersion/aggregation states upon the alternate bubbling of CO2 and N2 in pure water.
