Abstract

Langmuir-Blodgett films of hexadecylvinylbenzyldimethylammonium chloride (CVDAC) in a mixture with arachidic acid could be tranferred onto solid substrates as Y-type films. CVDAC could also be stabilized by complexation with sodium polysteresulphonate to give Z-type films. A 77.8 MHz surface acoustic wave (SAW) device deposited with CVDAC layers showed a nearly linear irreversible decrease in resonant frequency on exposure to ozone. The response rate was dependent on the number of layers deposited on the device and linearly dependent on the ozone concentration. The response of a device deposited with the complexed film was greater than for the mixed film.
