Formaldehyde Gas Sensor Based on Quartz Crystal Microbalance Modified with Aniline-Doped Polyvinyl Acetate Nanofibers
Summary
Electrospun polyvinyl acetate nanofibres doped with 2–6 wt% aniline make a QCM selective to formaldehyde in air. The best coating gave 0.056 Hz per ppm, response and recovery in 200 s and 90 s, and a detection limit of 28 ppm; the authors note this is still above the 2 ppm workplace limit and must come down for real monitoring.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
