Akustyczne badania polimeru typu RR-P3HT do wykrywania DMMP w powietrzu

This paper presents the preliminary investigations using the SAW method for the detection of trace amounts of DMMP molecules (Dimethylmethylphosphate) in air mixtures, which is commonly used to simulate the presence of warfare agents like sarin gas. The sensor element is a layer of photoconductive polymer poly(3-hexylphosphate) of regioregular type ((RR)-P3HT) produced by airborne sputtering on the free surface of the SAW module. An important factor enhancing the ability of DMMP detection was lighting of the polymer by means of a white light of a small incandescent lamp.
