Abstract:
The contribution presents novel research of textile chemiresistors prepared on textile substrates (Evolon and Polyester) equipped with graphite electrodes and sensitive layers based on polymer ionic liquid. The polymer ionic liquid, i.e. poly(tributylhexylphosphonium 3-sulfopropylacrylate) was in-situ polymerized on the textile substrates. The responses of such sensors to toxic gases (10 ppm of methanol, nitrogen dioxide, 4-bromoacetophenone and diethylmalonate) were then investigated in dc-mode of measurement – the reference was "pure" synthetic air. It was shown that sensor dynamics depends mainly on molecular weight of the analytes.
