Maltodextrin-overlaid polyvinyl acetate nanofibers for highly sensitive and selective room-temperature ammonia sensors
Summary
Polyvinyl acetate nanofibres on a QCM, overlaid with a thin maltodextrin coating, sense ammonia at room temperature. With a 0.05% overlay the sensitivity rises to 0.525 Hz per ppm, more than six times the bare fibres, with responses of about half a minute, a detection limit near 2 ppm, good selectivity and stable behaviour over 32 days of testing.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
