摘要

本研究开发了一种可调节内部孔隙率的亲水性海绵蒸发器，用于高效海水淡化和废水处理。亲水性涂层和内部孔隙率的调节实现了光吸收、光热转换、供水、蒸汽逸出和环境能量收集之间的平衡。这导致了3.89 kg m−2 h−1的高蒸发速率。此外，制备的海绵蒸发器在海水淡化和废水净化中具有良好的适应性和稳定性。海绵蒸发器有三个显著特点：易于制备，便携，效率高。这些特点为后续高效太阳能界面蒸发系统的优化奠定了基础。

Sponge-based evaporator with regulated hydrophilic coating and porosity structure for high-efficient desalination and wastewater purification

This study developed a hydrophilic sponge evaporator with regulated internal porosity for high-efficiency desalination and wastewater treatment. The modulation of the hydrophilic coating and internal porosity achieved a balance between light absorption, photothermal conversion, water supply, vapor escape, and environmental energy harvesting. This resulted in a high evaporation rate of 3.89 kg m⁻² h⁻¹. Additionally, the prepared sponge evaporator demonstrates excellent adaptability and stability in seawater desalination and wastewater purification. The sponge evaporator has three notable features: ease of preparation, portability, and high efficiency. These features lay the groundwork for optimizing subsequent high-efficiency solar interfacial evaporation systems.
