Polyaniline (PANi) is one of the most noteworthy conductive polymers because of the low cost of its synthesis, its conductive features when doped, and its thermal and environmental stability. This conducting polymer shows chemical selectivity, which allows it acting as excellent material for the immobilization of gas molecules, exhibiting highly reversible redox behaviour. Its sensing performances are well known in literature most of all for ammonia detection. Usually, higher potentialities of sensing materials can be realized making use of nanostructured elements. Electrospinning technique is a successful and easy method to assemble nano-structures (nanowires, nanobeads, nanotubes), as occurs in natural systems (biomimetic approach), in a single step, on appropriate transducers.
