摘要：
PEDOT:PSS/Fe(salen) composite thin films were coated on glass pieces with interdigitated Au electrodes by spin coating method for CO gas sensing application. The metal complex doped PEDOT:PSS film was experienced by some common atmospheric gases to examine its identification ability for CO gas detection. The highest response factor (Delta R/R-0 x 100) and lowest response time were gained -31.32 +/- 0.88% and 38 s, respectively. An optimum level of doping (0.1 wt.% of Fe(salen)) was established for the highest sensitivity. The results showed that the sensor response was reproducible (RD < 2%) and fast recovery (5 s) in dry atmosphere and room temperature. The Fe(salen)-doped PEDOT:PSS was well characterized by different techniques such as UV-vis and FTIR spectroscopy. In addition, the surface topography of Fe(salen) doped PEDOT:PSS film was investigated using AFIVI. The results of this study can be helpful in selecting appropriate procedure for utilizing PEDOT:PSS/Fe(salen) composite for effective gas sensing applications. (c) 2015 Elsevier B.V.
