Abstract

We present a new optical polymer thin film sensor for high sensitivity and rapid response gas detection. Amphiphilic polymer co-networks (APCN) are used as sensor matrices for fast nitrogen dioxide detection. The sensor consists of an APCN in which the indicator has been embedded. The APCNs were synthesized by free radical induced photo-polymerization and result in poly(2-(dimethylamino)ethyl acrylate)-l-polydimethylsiloxane (PDMAEA-l-PDMS).
