Study of the sorption processes in a piezoelectric-molecularly imprinted polymer film structure using Rayleigh surface acoustic waves

The sorption processes in a piezoelectric-molecularly imprinted polymer film structure, where the polymer is synthesized from the monomers of bisphenol-A glycerolate diacrylate using imprinted morpholine molecules as template molecules, are experimentally studied with Rayleigh surface acoustic waves at a frequency of 120 MHz. The desorption processes for morpholine are found to be anomalously slow as compared to other analytes under study. The possibility of the application of the results obtained for creating selective chemical sensors based on surface acoustic waves is discussed.
