Abstract
A new type of "smart" single-walled carbon nanotubes is created by wrapping a pyrene-labeled CO(2) -responsive polymer via π-π stacking. The polymer/SWNT hybrids not only undergo a hydrophobic-hydrophilic transition upon CO(2) stimulus of CO(2) in a mixed solvent, but also exhibit switchable dispersion/aggregation states upon the alternate bubbling of CO(2) and N(2) in pure water.
