Flexible Paper-Based Polyacrylic Acid-Coated Silver Nanoparticle Film Sensors Prepared by Inkjet Printing for Efficient Ammonia Detection at Room Temperature
Abstract:A series of disposable gas-sensing paper-based film sensors were prepared rapidly by inkjet printing polyacrylic acid-coated silver nanoparticle (PAA/AgNP) ink onto the ordinary copy paper. The surface morphologies and chemical structures of the printed PAA/AgNP based sensing films with various thicknesses and spacing widths of interdigital electrodes were characterized. The electrical properties and the gas sensing performance of the film sensors were investigated and the results showed that the PAA/AgNP film… Show more
