Synthesis of Nanostructured Conducting Polymers for Gas Sensing Application

Snehal Kargirwar

Polyaniline (PANI)–coated Polyacrylonitrile (PAN) (PANI/PAN) nanofiber was prepared with an electrospinning technique and in-situ chemical polymerization. The morphology and chemical structure of PANI/PAN nanofiber was characterized by scanning electron microscopy (SEM). SEM images shows that PANI as the shell layer was homogeneously and uniformly polymerized on the surface of PAN nanofiber. The effects of different concentrations of methanol and acetone on the responses of PANI/PAN nanofiber sensor at room temperature were investigated. The sensitivity of PANI/PAN was observed to increase with the increase in the concentration of methanol and acetone.
