Abstract
AbstractWe describe herein the construction of a simple, low‐power, broadly responsive vapor sensor. Carbon black‐organic polymer composites have been shown to swell reversibly upon exposure to vapors. Thin films of carbon black‐organic polymer composites have been deposited across two metallic leads, with swelling‐induced resistance changes of the films signaling the presence of vapors. To identify and classify vapors, arrays of such vapor‐sensing elements have been constructed, with each element containing a different organic polymer as the insulating phase. The differing gas‐solid partition coefficients for the various polymers of the sensor array produce a pattern of resistance changes that can be used to classify vapors and vapor mixtures. This type of sensor array has been shown to resolve all organic vapors that have been analyzed, and can even resolve H2O from D2O.
