Abstract
Fluoropolymer films deposited on quartz crystals by radio-frequency sputtering of polychlorotrifluoroethylene can be used for molecular sensing probes. For several organic materials, the piezoelectric responses of these sensing probes can be classified into characteristic categories. These responses are especially distinctive for highly fluorinated molecules. A film with highly halogenated frameworks shows slow sorption-desorption response to alternate exposures to acetone atmosphere and to air.
