ION CONDUCTING MATERIAL AND METHOD FOR PREPARATION THEREOF, AND ELECTROCHEMICAL DEVICE

摘要

An ion conducting material, which comprises a derivative comprising at least one carbonaceous material selected from the group consisting of a fullerene molecule, a cluster containing carbon as a main component and a linear or tubular carbon structure and an ionically dissociative group being bonded to the carbonaceous material, and a polymer of a material having a basic group; a method for preparing the ion conducting material which comprises a step of dissolving the above derivative and a polymer of the above material having a basic group into an solvent to form a uniform solution, and a step of removing the above solvent; and an electrochemical device which has a negative electrode and a positive electrode, and an ion conducting material sandwiched between the electrodes, wherein the ion conducting material comprises the above ion conducting material. The above ion conducting material is insoluble in water or in a fuel and can achieve stable ion conduction for proton and the like.
