A new material has been proposed as a chemosensitive layer in the surface acoustic wave sensor for vapors of some volatile organic solvents. This material has been fabricated from the bicomponent mixture of 5-[[1,3-dioxo-3-[4-(1-oxooctadecyl) phenyl] propyl] amino]-1,3-benzenedicarboxylic acid and cetylamine. In the Langmuir-Blodgett process a nanolayer of the mixture has been deposited on a piezoelectric substrate with interdigital transducers. Subsequently, the molecules of cetylamine have been removed from the layer leaving nanopores. Sensing properties of this layer for the vapors of some volatile organic solvents in air have been investigated.

Zaproponowano nowy materiał na warstwę chemoczułą czujnika do wykrywania par wybranych lotnych rozpuszczalników organicznych, wykorzystującego akustyczną falę powierzchniową. Materiał ten został wytworzony z dwuskładnikowej mieszaniny kwasu 5-[[1,3-diokso-3-[4-(1-oksooktadecylo) fenylo] propyl] amino]-1,3-benzenodikarboksylowego i cetyloaminy. Osadzono nanowarstwę tej mieszaniny na podłożu piezoelektrycznym z przetwornikami międzypalczastymi stosując proces Langmuira-Blodgett. Następnie cząsteczki cetyloaminy zostały usunięte z warstwy pozostawiajac po sobie nanopory. Zbadano wrażliwość tej warstwy na pary wybranych lotnych rozpuszczalników organicznych w powietrzu.
