We have synthesized Polyaniline nanoparticles and nanofibers using chemical oxidation method and tested them for their Hydrogen sensing properties. PANI nanoparticles and nanofibers have demonstrated sensor response of 1.38 and 1.52, respectively. Reaction kinetics has also enhanced in case of PANI nanofibers with response and recovery times of 170 and 95 s, respectively. The increased conductivity, sensor response and reaction kinetics in case of the nanofibers as compared to nanoparticles is attributed to the 1-D conductive channel provided by the nanofibers for faster and better electron transfer.
