从雾流中收集水正在成为解决缺水问题的一种有希望的解决方案。这项工作展示了一种新型环保集水器，由自制的Janus聚乙烯醇海绵与双向形状记忆合金弹簧组合而成，将传统的静态集水方式转变为动态集水方式。 Janus 结构的单向水输送与动态收集方法相结合，使水收集率 (WCR) 提高了 30.8%。由此产生的 WCR 高达 5.1 g/h，与同类研究相比排名较高。光和热响应能力、易于制造和良好的循环性能表明我们的器件可用于各种应用。在这项工作中，推荐了一种高效、智能自适应、准备简单、精确制导且经济的集雾装置。我们的工作为高效实用的集水器的设计提供了新的见解。
Collecting water from fog flow is emerging as a promising solution to the water shortage problem. This work demonstrated a novel environmentally responsive water collector made from a self-prepared Janus polyvinyl alcohol sponge in combination with a two-way shape memory alloy spring, which transforms the traditional manner of static water collection into a dynamic one. The unidirectional water transport of the Janus structure together with the dynamic collection approach correspond to a 30.8% increase in the water-collection rate (WCR). The resultant WCR is up to 5.1 g/h, which ranks relatively high compared to similar studies. The light- and thermal-response capability, easy fabrication, and good cycling performance indicate that our devices could be utilized in a variety of applications. In this work, an efficient, intelligent adaptive, simple-preparation, precision-guided, and economical fog-collecting devices are recommended. Our work provides new insights on the design of high-efficient water collectors with practicability.
