Abstract:
A high-throughput method for evaluating a barrier property of an array of coatings, the method comprising:providing a plurality of acoustic wave devices, wherein each of the plurality of acoustic wave devices comprises at least one surface; providing a plurality of coating materials suitable for forming a plurality of coatings on the at least one surface of each of the plurality of acoustic wave devices; coating each of the plurality of acoustic wave devices with at least one of the plurality of coating materials to form a plurality of coated acoustic wave devices; measuring a predetermined output parameter of each of the plurality of coated acoustic wave devices; exposing the plurality of coated acoustic wave devices to an analyte vapor of a predetermined concentration; measuring the predetermined output parameter of each of the plurality of coated acoustic wave devices; and correlating a change in the predetermined output parameter of each of the plurality of coated acoustic wave devices to the barrier property of each of the plurality of coatings.
