The viscosity of the nanocomposite as a function of the a- MWCNT amount was characterized via Brookfield-HBDV-E, 27 spindle for screen printing. Raman spectroscopy (Renishow, RM-1000 Invia), with an excitation energy of 2.41 eV, was
performed to investigate the damage on the graphite flakes during the experimental procedure.
