The fabrication of PVP/NiAc nanofiber as a QCM active layer for hazardous vapor detection
Summary
Electrospun composite nanofibres of PVP and nickel acetate, about 1 µm across, are used as the sensing layer of a QCM for hazardous vapours. Tested at 5–22.5 ppm, the sensor responded most to methanol (2.35 Hz/ppm), then formaldehyde, acetone and dimethylacetamide; Scatchard, Freundlich, Langmuir and Langmuir–Freundlich models were fitted to describe the physical adsorption.
