N2 - The reaction of sp2-hybridized carbons of CNTs with poly(2-vinylpyridine) (poly2VP) chains terminated with the 2,2,6,6- tetramethylpiperidinyl-1-oxyl (TEMPO) radical-stabilizing group is reported. The modified CNTs are recovered by filtration through a 0.2 μm teflon membrane. CNT-g-P2VP is dispersed in acidic water in order to completely remove possible traces of non-grafted poly2VP chains. It is observed that the positively charged poly2VP shell is responsible for the selective deposition of CNTs onto oppositely charged surfaces.
