Polyacrylonitrile (PAN) nanofiber deposited on quartz crystal microbalance (QCM)
substrate as solvent vapor sensing has been successfully developed. The absorption and
swelling behavior has been assumed to be responsible for sensing mechanism in vapor sensing.
In this study, we aim to investigate the correlation between the swelling degree (polymersolvent
affinity) and the sensor response. The PAN nanofiber has been successfully deposited
on QCM substrate with relatively homogenous nanofiber diameter about (260 ± 20) nm. The
tests vapor solvent was included dimethylformamide (DMF), dimethylacetamide (DMAc),
ethylene glycol (EG), toluene, ethanol, and distilled water. The results indicated that the sensor
response for various vapor solvent clearly influences by its polymer-solvent affinity. The
highest sensor response was achieved with DMF vapor due to its highest affinity with PAN
polymer. The swelling behavior of polymer can be a potential candidate for developing vapor
sensors with a polymer as an active layer.
