Efficient Water Mist Collector with Both a Kirigami Structure and Chemical Modification

The shortage of freshwater resourcesis a common problem facedby people all over the world. Water mist collection provides a feasiblesolution to this problem. In this paper, three kinds of foggers witha kirigami structure and chemical modification were prepared. Theirfog collection efficiencies were 3.04, 3.17, and 3.54 g center dot h(-1)center dot cm(-2), respectively, whichwere 1.57, 1.63, and 1.82 times that of the original zinc sheet. Then,the fog collector of sample 3 with the highest fogging efficiencywas analyzed and discussed. In order to evaluate the practical applicationof the sample, durability and ultraviolet (UV) resistance tests ofthe sample were carried out. The experimental results show that thesurface of sample 3 has better durability and excellent UV resistance.In addition, the fog collector design incorporating readily availablematerials and a straightforward preparation process showcases outstandingefficiency. As such, it presents a novel approach for the developmentof high-performance fog collection systems in the future.

Automated summary

The shortage of freshwater resources is a global problem. This study proposes a solution using foggers with a kirigami structure and chemical modification, which have shown excellent fog collection efficiency, durability, and UV resistance.
