For the SWCNT devices, the PE membrane
was infiltrated with the ionic liquid by adding 100 μL per cm2 and letting it soak for 10 min. The previously prepared dispersion
was spray-deposited with an airbrush at 3 bar at a distance of 15
cm through an appropriate stencil. The amount of material deposited
was controlled by the volume of dispersion sprayed onto the substrate.
The area was approximately 50 cm2, and the volumes were
in the range of 0.5–10 mL. This was done on a hotplate at 90
°C. No attempt to remove the carboxymethyl cellulose stabilizer
was made to facilitate a straight-out-of-the-bottle approach. Electrical
connection to the potentiostat was made through copper tape. Sheet
resistance of the films was measured using a sacrificial piece of
film on the substrate and the transmission line method.
