| The responsive nature of polyaniline (PANI) to gaseous pollutants is highly dependant on the film composition and processing. In initial studies LEB-PANI was used to develop a room temperature sensor for NO2 detection. It has been observed that the relative response to NO2 in constant humidity is dependant on the concentration of polyaniline in electrospun films of PANI and poly-vinyl-pyrrolidone (PVP). In subsequent studies analysis of exposed bio-doped PANI/PVP matrices reveal PANI particles self assembling into hollow fibrous structures. In this paper the results from initial efforts for the development of a PANI based bio/chem sensor are discussed. |
