AI Technical Summary
Traditional ion exchange membranes suffer from high ion transport resistance due to their structural characteristics, which prevents efficient and low-resistance transport and limits the industrial application of salinity gradient energy.
Two-dimensional nanosheets are surface modified with a modifier, and the hydration shell of the target ions is stripped away through specific binding or spatial confinement to prepare a dehydrated drag-reducing ion exchange membrane, thereby achieving efficient migration of bare ions within the membrane.
It significantly reduces membrane resistance, increases power density, and achieves low-resistance, high-efficiency ion transport, breaking through the conversion efficiency bottleneck of traditional membrane materials. It is suitable for salinity gradient energy capture systems at the confluence of river and seawater.
