Transport properties of the new polytriazole and polynaphthalenediimide membrane materials have been observed. According to impedance data, the sulfonated polynaphthalenediimide membrane obtained in dimethylsulfoxide demonstrates the maximum value of ionic conductivity. Modification of a membrane material with silica leads to transport properties improvement.
