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

The shortage of freshwater resources is a common problem faced by people all over the world. Water mist collection provides a feasible solution to this problem. In this paper, three kinds of foggers with a kirigami structure and chemical modification were prepared. Their fog collection efficiencies were 3.04, 3.17, and 3.54 g·h-1·cm-2, respectively, which were 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 efficiency was analyzed and discussed. In order to evaluate the practical application of the sample, durability and ultraviolet (UV) resistance tests of the sample were carried out. The experimental results show that the surface of sample 3 has better durability and excellent UV resistance. In addition, the fog collector design incorporating readily available materials and a straightforward preparation process showcases outstanding efficiency. As such, it presents a novel approach for the development of high-performance fog collection systems in the future.
