The article presents pioneering research of textile chemiresistors on Evolon and Polyester sub-strates equipped with graphite electrodes and in-situ polymerized poly(tetrabutylphosphonium3-sulfopropylacrylate) or poly(tributylhexylphosphonium 3-sulfopropylacrylate) sensitive layers. TheDC- and AC- responses to 10 ppm of methanol, nitrogen dioxide, 4-bromoacetophenone, diethylmalonateand yperite were then investigated at laboratory temperature – the reference was “pure” synthetic air.Under these circumstances the DC- responses (SDC) varied from 0.48 to 1.36 and maximum AC- responses(Spa) from 8 to 26 deg. It was shown that sensor dynamics depends mainly on molecular weight of theanalytes. Moreover, the magnitude of AC-responses correlated both qualitatively and quantitatively withthe dipole moments of the analyzed molecules.
