Annealing treatment and carbon nanotubes concentration effects on the optical and vibrational properties of single walled carbon nanotubes functionalized with short oligo-N-vinyl carbazole

▶ Functionalization of single walled carbon nanotubes with oligo-N-vinylcarbazole. ▶ Use of IR, Raman, optical absorption and PL to argue the grafting process. ▶ By referring to the chloroform, chlorobenzene induces a more dispersion process. ▶ Non-covalently homogenous dispersion process for concentrations lower than 1.1%. ▶ Annealing at 333 K induces a covalent bonding for SWNTs concentrations less than 1.1%.
