This paper presents acetone vapor sensing properties of WO(3) thick films. In this work, the WO(3) thick films were prepared by standard screen-printing method. These films were characterized by X-ray diffraction (XRD) measurements, and scanning electron microscopy (SEM). The acetone vapor ...

of polymethylmethacrylate (PMMA) useful for detecting chemical agents such as acetone, methanol, and isopropyl alcohol (IPA) is presented. Swelling of the cured PMMA polymer layer in the presence of acetone, methanol, and isopropyl to the concentration of chemical vapor present within the sensing chamber. For ...
