The purpose of this work is to study the influence to the spatial conformation of a polymer grafted onto multi-walled carbon nanotubes (MWCNT) according to the differing electronic distribution of the polymer?s repetitive unit. In this work, we made a graft-from functionalization using as monomers: 4-vinylpyridine (monomer with an aromatic substituent) and acrylonitrile (monomer with a non aromatic, where the substituent is a nitrile group). The functionalization efficiency was studied by spectroscopic and thermal technique. The spacial conformations of the polymer around carbon nanotubes were studied by high resolution transmission electron microscopy (HRTEM).
