Abstract

A highly sensitive ammonia sensor based on poly(acrylic acid)-doped polyaniline was fabricated by means of vapour phase deposition polymerization. The sensitive layer was polymerised in situ on the flexible Kapton® substrate incorporating interdigitated gold electrodes. The sensor shows sensitive and fast response toward very low concentrations of ammonia vapour at room temperature. The improved sensing performance was attributed to the nanoporous structure of the sensing layer at the surface.
