In this study, ion exchange membranes were prepared. Prior to the preparation of the ion exchange composite membranes, sulfonation and amination were performed with different equivalents to the same polymer. Then, the most suitable equivalent amount of polymer was selected from the completed polymers. The selected polymer was impregnated into support and reinforced composite membrane excellent in mechanical strength was prepared. When the support was used, the ion exchange capacity value is lowered. In order to compensate, particles were mixed together in polymer solution to maintain the performance. FE-SEM was used to confirm that the particles were sell dispersed in the membrane, FT-IR was used for quantitative analysis, TGA/DSC for thermal characterization and Ion conductivity / membrane resistance / I-V curve were measured for electrochemical properties.
