Flexible NO gas sensor based on conducting polymer poly[ N -9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT)

Flexible gas sensor for Nitric Oxide (NO) detection has been realized using conducting polymer poly[N-9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT) as the gas sensing material. This has been achieved by the deposition of PCDTBT on flexible BOPET substrate using the simple technique of spin coating. PCDTBT has been found to be highly selective for NO gas with a very good response for upto 5 ppm...
