Specialized fabric reduces energy needed to evaporate seawater for desalination
In short: Researchers have developed a hierarchical fabric made of polyacrylonitrile and copper sulfide that can turn seawater into fresh water using sunlight. This 'heliotropic' evaporator allows seawater to flow through the material, achieving high evaporation rates while preventing the salt crystallization that typically clogs traditional solar desalination systems.
The fabric's structure disrupts hydrogen bonds at the copper sulfide interfaces, lowering the energy required for evaporation compared to pure water. When tested under solar irradiation, the model maintained a steady evaporation rate even as sunlight angles shifted, unlike traditional floating models which saw significant performance drops.
The study used a prototype model where seawater flows from high to low through the fabric, though the research focuses on the efficiency of this specific prototype under controlled solar conditions.
Why it matters: This fabric design could enable more efficient, continuous solar-powered desalination by preventing salt buildup.
