Surface Modification of Multi Walled Carbon Nanotubes Via Transfer Nitroxide –Mediated Radical Polymerization

functionalization of carbon nanotubes via grafting polymer [1] is an efficient way to promote solubility of CNTs in common solvent. The approach employed involves the followingsequence of procedures: at first Nanotubs surface modified under acidic condition, reduction of formed carboxyl groups insurfaces nanotubes carry out by lithium aluminum hydride, to perform ATRP polymerization [2] α-Phenyl Chloro acetyl chloride , attached to hydroxyl group, Surface-initiatedpolymerization of 4-chloro methyl styrene from the terminal chloride on the surface-bonded Cl-MWCNT,The nitroxidemediatedradical polymerization of styrene was carried out on the surfaces of multiwalled carbon nanotubes intitiated by anMWNT-supported initator multiwalled carbon nanotube -2 ,2 ,6 ,6 –tetramethylpiperidin.[3] (scheme1).
