| 摘要 |
A reactive gas sensor which utilizes an electrically conductive polymer composite which comprises an inner layer of an electrically conductive polymer, intermediate layers of a polymer which exhibits a low degree of gas permeability, and protective outer layers of a polymer which exhibits a low degree of moisture permeability. The preferred polymers for the intermediate layers are ethylene vinyl alcohol copolymers and polyvinylidene chloride. The sensor also includes means for measuring the resistance of the electrically conductive polymer.
