An ion-exchange membrane (IEM) has been employed in numerous electrochemical systems such as water splitting, fuel cells, and ammonia synthesis. The IEM generally allows to penetrate the desired ions and to block unwanted ions through the system. Currently, commercial Nafion®-based IEMs have been widely adopted either in industrial or academic fields. However, they need to overcome some important issues such as dimensional instability, weak chemical resistance, and low ion permeability. As alternatives, several polymers have been proposed to address these problems. In line with effort, we here report a new type of IEM, which is physicochemically modified nanocelluloses to introduce ion permeation ability. We have used a side-bi-side custom diffusion cell to measure ion permeation. Furthermore, we have attempted to relate ion permeability with physicochemical features of the modified nanocellulose. Further information will be detailed in this poster. |
