Abstract
The effect of ion irradiation and thermal annealing on electrophysical properties of multi-walled carbon nanotube (MWCNT) network have been studied. The morphology and structure of MWCNT networks have been studied by means of SEM and Raman spectroscopy. It is shown that irradiation causes formation of defects in the structure of MWCNT. Annealing leads to partial recovery of the structure of MWCNT. Electrophysical measurements indicate an effect of internal structure transformation on the resistance of MWCNT networks. The increment of the resistance of MWCNT networks after treatments is observed. It is shown that the combination of ion irradiation and thermal annealing effectively manage the electrophysical properties of MWCNT networks.
