Self-assembled films of multi-wall carbon nanotubes used in gas sensors to increase the sensitivity limit for oxygen detection

We have developed a self-assembly method to obtain multi-wall carbon nanotube films applied in resistive gas sensor devices. This self-assembly method produces a homogeneous multi-wall carbon nanotube film with good adhesion to the substrate and an oxygen sensor device with a sensitivity 3.4 times h...

Zusammenfassung:	We have developed a self-assembly method to obtain multi-wall carbon nanotube films applied in resistive gas sensor devices. This self-assembly method produces a homogeneous multi-wall carbon nanotube film with good adhesion to the substrate and an oxygen sensor device with a sensitivity 3.4 times higher than films made by regular casting deposition. A fast recovery time of 0.9s was observed at 160°C operation temperature.
