A new class of sensor-oriented composite conducting thin films was grown utilizing an original method. The technique is based on the chemical polymerization of pyrrole (PY) vapours onto an oxidizing salt pattern obtained via chlorination of a co-sputtered granular metal thin film. Time stability of the samples realized with this technological approach and their response to exposure to different atmospheres were studied; the behaviour of the material subjected to mechanical strain was also investigated.

Abstract
A new class of sensor-oriented composite conducting thin films was grown utilizing an original method. The technique is based on the chemical polymerization of pyrrole (PY) vapours onto an oxidizing salt pattern obtained via chlorination of a co-sputtered granular metal thin film. Time stability of the samples realized with this technological approach and their response to exposure to different atmospheres were studied; the behaviour of the material subjected to mechanical strain was also investigated.File in questo prodotto:
