The Biginelli reaction has been utilized as an effective click reaction to collaborate with pi-pi stacking to prepare carbon nanotube-polymer conjugates. The synthesized polymers are successfully anchored on carbon nanotube surface via 'grafting to' strategy, and the obtained carbon nanotube-polymer composites possessing characteristic properties of anchored polymer can be well dispersed in general solution to expand carbon nanotubes application realm.
