A conductometric microsensor for measuring methanol vapor was conceived, based on electrospun composite nanofibers of polyvinyl chloride (PVC) doped with nickel phthalocyanine (NiPc) deposited interdigitated electrodes (IDEs) as transducers. The nanofiber’s shape, structure, percent atomic content and thermal properties were studied. sensor showed good sensitivity (505µS.cm?1.(v/v)?1), low limi...
