Abstract
Preparation and properties of reticulate doped polymers containing BEDT-TTF polyiodide crystalline network are discussed. The highly conducting films are obtained using different methods, including recently developed one in which oxidation of the donor with iodine and crystallization of the resulting salt take place simultaneously in situ, in the swollen polymer matrix. It was found that the temperature dependence of conductivity of the separated microcrystal grown in the film exhibits metallic character with a maximum around 100K. The conductivity of the as-obtained composite increases with temperature up to ca. 120K with an activation energy of ca. 50 meV, then levels off. Annealing of the composites in order to transform the BEDT-TTF polyiodide crystalites into superconducting [beta][sup *]-phase causes dramatic changes in the conductivity behaviour; the [sigma](T) dependence of the composite switches from semiconductor- to metal-like. Stability of the films at ambient conditions is good. (orig.)
