AI Technical Summary
Existing materials have poor mechanical properties in salinity gradient power generation, making it difficult to fabricate on a large scale and resulting in insufficient power, which affects energy conversion efficiency.
Two-dimensional oriented nanochannels are constructed using self-supporting liquid crystal materials, especially smectic or nematic liquid crystals, and carboxyl groups are connected by hydrogen bonds to prepare films with a thickness of 5-50 μm for salinity gradient power generation. Combined with alkali treatment, the nanochannels are made negatively charged to improve ion selectivity and transport efficiency.
It achieves efficient salinity gradient energy conversion, improves the power density of salinity gradient power generation, and the material has good mechanical strength and flexibility, making it suitable for large-scale applications.
