SWNTs have been successfully grafted with polyisoprene (PIp) via anionic polymerization initiated by carbanion-bearing SWNTs. Carbanions were fixed on SWNTs by treating SWNTs with sec-butyllithium, and then the PIp chains grew from these carbanion. The polymer chains were covalently attached to the SWNTs, which leads to the coating of carbon nanotubes and finally to the destruction of the nanotube bundles.
