Mgh. Meijerink et al., Reproducible fabrication of an array of gas-sensitive chemo-resistors withcommercially available polyaniline, SENS ACTU-B, 68(1-3), 2000, pp. 331-334
Polyaniline, which was obtained as a dispersion from a commercial supplier,
was used to prepare chemo-resistors, The sensors were prepared in a batch
process by spin coating on a wafer with Au interdigitated electrode arrays
(IDAs). The gas response behaviour of the so-prepared sensors could be modi
fied by a post-treatment with organic solvents to obtain an array of suffic
iently different sensors for the successful recognition of five different v
apours. The preliminary fabrication procedure showed a good batch-to-batch
reproducibility, as well as an excellent stability of the sensor responses.
