A sensor for chlorine gas detection, consisting of an amphiphilic polymer co-network with an immobilised oxidation indicator, o-tolidine, is described. Data describing gas sensing properties and long-term stability will be presented. This study focuses on APCN thin films as a matrix for indicator immobilisation. Thin films of poly(2-hydroxyethyl acrylate)-l-polydimethylsiloxane PHEA-l-PDMS were prepared as immobilisation matrices for o-tolidine. We present a simple, non-expensive, but highly sensitive optical sensor for chlorine gas detection. The thin film response is reproducible and irreversible. With our kinetic-optical method rapid response times were achieved. The determination of chlorine is performed on the basis of the oxidation of o-tolidine as the chromogenic reagent to a coloured product which can be monitored at 650nm. The results reveal a fast response to chlorine gas down to concentrations of 0.01ppm.
