Recent studies have shown that the electrical conductivity of certain organic polymer films change when the films are exposed to organic vapors. Here, results using polymers that conduct via redox hopping and conjugated polymers such as polyaniline are emphasized. In these cases extremely large vapor‐induced increases in conductivity, up to a factor of 10 6 , have been measured. These vapoconductivity effects result in part from morphological changes, especially plasticization. The results are of interest for the development of sensors.
