We grafted polymers on the surface of CNT via Atom Transfer Radical polymerization in two independent approaches, graft-from and graft-onto methods. In the first method, ATRP initiation group was introduced to the surface of CNTs to graft polymer from the surface. Secondly, radicals formed at the chain end of polymers prepared by ATRP added onto the surface of CNTs. Obtained CNT-polymer composites showed improved dispersion stability in organic solvents and grafted polymer on the CNT surface was verified by TEM measurement.
