Abstract

Highlights

Micro–nano water film enhanced interfacial solar evaporator enables a high evaporation rate of 2.18 kg m⁻² h⁻¹ under 1 sun.
An outdoor device with an enhanced condensation design demonstrates a high water production rate of 15.9–19.4 kg kW⁻¹ h⁻¹ m⁻².
A multi-objective predictive model is established to assess outdoor water production performance.

微纳米水膜实现高性能界面太阳能蒸发。

界面太阳能蒸发对解决淡水短缺问题有很大的前景。然而，大多数界面太阳能蒸发器在整个蒸发过程中总是充满水，从而带来不可避免的热损失。在此，我们提出了一种基于微纳米水膜的新型界面蒸发结构，该结构的蒸发性能显著提高，并通过聚吡咯和聚多巴胺涂层的聚二甲基硅氧烷海绵进行了实验验证。基于所制备的海绵的2D蒸发器通过微调界面微纳水膜，在1个太阳下实现了2.18kg m-2 h-1的增强蒸发速率。然后，设计了一种具有增强冷凝功能的自制设备，用于户外清洁水生产。在40天的连续测试中，该装置表现出15.9-19.4kg kW-1 h-1m-2的高产水率（WPR）。基于室外结果，我们进一步建立了一个多目标模型来评估全球WPR。据预测，1平方米的设备每天最多可生产7.8公斤清洁水，可满足3人的日常饮用水需求。最后，这项技术可以通过进一步的大规模应用，极大地缓解当前的水和能源危机。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
