Abstract

Gas sensors are now widely used for routine monitoring of the quality of atmospheres. A sensitive PEDOT: PSS/Fe(salen) THIN FILM based toxic gas sensor deposited on glass pieces with interdigitated Au electrodes was developed by the spin coating method. The obtained composite was well characterized by different techniques such as UV– vis spectroscopy and FTIR. Also, the surface topography of THIN FILM composite was investigated using AFM. The Fe(salen)-doped PEDOT: PSS on interdigitated electrode was experienced an immediate decrease in resistance when exposed to CARBON MONOXIDE gas under normal dry room temperature conditions (%RH=20). The results showed that the response of desired sensor was not unidirectional, and reverses to the original resistance level when CO was removed from the test chamber (RD< 2%). The highest response factor and lowest response time (t90) obtained were equal to 40± 0. 77% and 38s, respectively. Ultimately, the optimum level of doping (0. 02 wt. % of Fe(salen)) was determined.
