era in materials science [1]. These incredible structures exhibit aseries of remarkable electronic, magnetic and mechanical proper-ties, extremely high aspect ratios while being at least 100 timesstronger than steel, but only one-sixth as heavy [2–4]. However,due to the high Van der Waals attractive forces acting on their sur-faces, of the order of 500 eV/m per m of tube–tube contact [5],their very high surface areas and high aspect ratios, CNTs tend toentangle even without external stimulus hence appearing highly
