Electrospun PVC-nickel phthalocyanine composite nanofiber based conductometric methanol microsensor

Résumé

A conductometric microsensor for measuring methanol vapor was conceived, based on electrospun composite nanofibers of polyvinyl chloride (PVC) doped with nickel phthalocyanine (NiPc) deposited on interdigitated electrodes (IDEs) as transducers. The nanofiber's shape, structure, percent atomic content and thermal properties were studied. The methanol sensor showed good sensitivity (505µS.cm-1 .(v/v)-1) , low limit of detection (LOD = 15 ppm), short response time (13 s), and short recovery time (25 s). The sensor was 4 times more sensitive to methanol than to ethanol and 19 times more sensitive to methanol than to acetone. Furthermore, the sensor response was unaffected by the interfering water vapor, making it more suitable for volatile organic compound (VOC) sensing in the presence of humidity. The sensor was applied for conductometric detection of methanol in rubbing alcohol.
