Detection of chemical warfare agents using surface acoustic wave sensors with different polymer coatings

Surface acoustic wave sensors (SAWS) with polymer based sensitive films were developed for detection of chemical warfare agents (CWAs). As polymers were used polybutadiene, polyisoprene, polydimethylsiloxane and polyethylenimine. The sensor was “delay line” type, deposited on quartz substrate, with 69.4 MHz central frequency. As CWAs were tested… (More)
