ClearDual-Functional Evaporator: Synergistic Seawater Purification via Photothermal Evaporation and Microplastic Adsorption
A novel solar-powered device tackles two pressing problems at once: freshwater scarcity and microplastic contamination in water. The evaporator uses sunlight to generate steam for desalination while a specially coated fiber layer adsorbs microplastics from the water before it evaporates — achieving 99.2% microplastic removal efficiency and a strong evaporation rate. Because the steam produced contains no microplastics, the design elegantly separates clean water production from plastic capture in a single low-energy system.
