Abstract
This chapter discusses the research efforts aimed at investigating and understanding the use of conducting polymers to monitor volatile chemicals. In some cases, the work led to commercial exploitation. The mechanisms of interaction between the polymer surface and the volatile chemicals give rise to electrical changes in the polymer that are not fully understood. The major advantages accrue from interrogating conducting polymers using high frequency techniques rather than the dc methods used by most researchers. Comparisons between the dielectric properties of the sensors predicted by the model and the number of measurements used to justify the model structure is done. Conducting polymer array technology, methods of interrogating sensor arrays, and their deployment as part of new sampling strategies are aimed at achieving parts per trillion (ppt) levels of detection for contamination in water using headspace analysis.
