The transmission of organic group in solid electrolyte film

We found a new solid electrolyte K-Cu-I thin film which can transmit the organic group (OG). The film was prepared by depositing a mixture of KI and CuI powders on heated glass substrate in vacuum. Under direct current (DC) electric field, the OGs can migrate toward cathode through the K-Cu-I film and congregated at the edge of the cathode. At room temperature, the film had an OG conductivity that can reach up to 0.15Ω-1cm-1 when the electron conductivity was ignorable (σ≤10-4Ω-1cm-1).
