This contribution presents results of development of textile chemiresistors for detection of chemical warfare agents [1-2]. Such sensors are intended as parts of smart textiles. The bearing part of sensor is constituted from a woven non-conductive textile - and equipped with screen-printed graphite electrodes. The gas sensitive layer is composed of the polymeric ionic liquid based on Poly(Tributylhexyl phosphonium 3-sulfopropyl acrylate). Subsequently, responses of textile chemiresistors to 10 ppm of four toxic gases or simulants of chemical warfare agents (methanol, nitrogen dioxide, diethyl malonate, 4-bromacetophenone) were measured in the dc-mode and acmode. The best achieved DC-response SDC = Rair/Rgas is SDC = 1.8 to 10 ppm of 4-bromacetophenone. The results of AC-measurements are presented as Nyquist plots.
