AT-cut thickness-shear mode quartz crystal microbalance (QCM) sensors and resonant piezo-layer (RPL) sensors made by lead zirconate titanate (PZT) thick films were sensitized with cavitand coatings (Qx-Cav and Me-Cav) and exposed to organic vapors of environmental interest. Responses at different temperatures are compared. Effects due to the temperature dependence of the partition coefficient and the porosity of RPL sensors are also considered.

Abstract
AT-cut thickness-shear mode quartz crystal microbalance (QCM) sensors and resonant piezo-layer (RPL) sensors made by lead zirconate titanate (PZT) thick films were sensitized with cavitand coatings (Qx-Cav and Me-Cav) and exposed to organic vapors of environmental interest. Responses at different temperatures are compared. Effects due to the temperature dependence of the partition coefficient and the porosity of RPL sensors are also considered.File in questo prodotto:
