- Abstract
- The response to relative humidity (RH) and alcohol vapors of resistive-type sensors based on
nanobeads of conjugated polymers, namely polyphenylacetylene (PPA) and copolymer
poly[phenylacetylene-(co-2-hydroxyethyl methacrylate)] (P(PA/HEMA)), were investigated.
Sensors based on ordered arrays of these nanostructured polymeric materials showed stable and
reproducible current intensity variations in the range 10-90% of relative humidity at room
temperature. Both polymers also showed sensitivity to aliphatic chain primary alcohols, and a
fine tuning of the sensor response was obtained by varying the chain length of the alcohol in
relation to the polarity. The nanostructured feature of polymeric-based membranes seems to
have an effect on the sensing response and an enhancement of the sensitivity was observed for
the response to water and alcohol vapor variations with respect to previous studies based on
amorphous polyphenylacetylene. High stability of the polymeric nanostructured membranes
was detected with no aging after two weeks in continuum stressing measurement conditions. (literal)
