Are Semiconducting Polymers Polymeric Semiconductors?: Polyaniline as an Example of “Conducting PolyPeierls ground state, and commensurability. The dominant defect states present upon doping, solitons, polarons and bipolarons, are discussed. Application of these concepts to polyaniline is made with emphasis on the mechanism for the insulator-to-metal transition.

Ionically-Conductive Solid Solutions of Divalent Cation Salts in Poly(Ethylene Oxide)and the conductivity of PbBr..(PEO). is 10. − 10. (ohm cm). at 180°C and about 10. (ohm-cm). at 250°C. The lead halide complexes conduct both Pb. and halide anions. All of the divalent halide complexes are stable to nearly 300°C.

Room Temperature High Ionic Conductivity from Alkali Metal — Silver Halide — Poly(Ethylene-Oxide) Co eV. Studies using differential scanning calorimetry, NMR and wide angle x-rays have been made and show that these complexes are polycrystalline but with no evidence of crystalline poly(ethylene-oxide). We suggest that the long polymeric chains inhibit the attainment of the positive activation volume required for disproportionation.

High Conductivity in an Amorphous Crosslinked Siloxane Polymer Electrolyteex impedance studies, DSC, and X-ray powder diffraction have been used to characterize the electrolyte. The temperature dependance of the conductivity has been modeled by the Vogel-Tammann-Fulcher equation.

Devices based on conducting polymers may thus offer advantages in environmental monitoring over presently available semiconductor sensors which generally operate at elevated temperatures.
