- Single-walled carbon nanotube (SWCNT)/Nafion composite films were fabricated on an
interdigitated electrode by using a simple casting method. Nafion acts as a polymer backbone
to give stable and homogeneous cast thin films. The potential use of the composites
as sensors of methanol concentration in water was investigated. The composites are operative
even at ambient temperatures, and respond quickly to concentration changes. The
resistance increases significantly with increasing concentration between 0.5 M and 4 M.
The composites may be useful as a material to measure the concentration of methanol
for direct fuel cells.
