Sensitive formaldehyde detection with QCM sensor based on PAAm/MWCNTs and PVAm/MWCNTs
Summary
Two formaldehyde sensors made by coating a QCM with composite films of polyacrylamide or polyvinylamine and multi-walled carbon nanotubes. The polyvinylamine version detects down to 0.5 ppm; the authors compare film proportions, reuse, selectivity and room-temperature response, and stress that both sensors are fast, cheap and easy to make.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
