Multi-Walled Carbon Nanotubes Printed Onto Polycarbonate Substrate for Electrochemical Sensing

Multi-walled carbon nanotubes were printed onto polycarbonate substrate by means of mass flexographic printing process and the potential application of printed carbon nanotubes-based films in electrochemical sensing was examined. In order to examine the effect of defects of nanotubes on their electrochemical response, two different types of printed films were fabricated containing carbon nanotubes with diverse degrees of defects. The findings demonstrate that the nanotubes defects improve the electrochemical response, the detection ability, and the sensitivity of printed carbon nanotubes-based films. The results strongly suggest of using mass-printing techniques for constructing low-price, precise and disposable carbon nanotubes-based films for sensing purposes.
