摘要: We have made measurements of the effect water vapour, oxygen and nitrogen on temperature-dependent conductivity polypyrrole gas sensors. Oxygen had little effect, while vapour decreased increased temperature dependence, consistent with hopping between localized states. No evidence was found any metallic term in our samples, strong contrast to case polyaniline. analyze previous for polyaniline exposed same gases, showing that remains general expression polymer a significant term.
