Quartz Crystal Microbalance Coated with a Polyvinylpyrrolidone Microfiber Active Layer as a High-Performance Acetic Acid Gas Sensor
Summary
A QCM coated with electrospun polyvinylpyrrolidone microfibres detects acetic acid vapour, a common and irritating airborne contaminant. The sensor reaches about 4.1 Hz/ppm, responds in 75 s and recovers in 66 s, and is repeatable, stable over time and selective for acetic acid; the authors note that its reversibility still needs work before use in real environments.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
