Coordinating the processes of droplet seize, transport, and shedding throughout fog harvesting stays a major problem. On this examine, we ready a copper mesh with various wettability by chemical etching and thiol modification. The Cu(OH)2 needle buildings on the floor of the samples have been characterised utilizing subject emission scanning electron microscopy (FE-SEM) and energy-dispersive X-ray spectroscopy (EDS). Moreover, the floor chemistry of the samples was analyzed utilizing infrared spectroscopy and X-ray photoelectron spectroscopy (XPS). A Janus membrane matchbox fog collector with directional transport properties was designed and assembled, successfully enhancing fog seize effectivity whereas facilitating the directional transport of fog droplets throughout a grid. We constructed a fog harvesting take a look at rig within the laboratory and evaluated the samples at a fog stream price of 0.8 m•s⁻¹. The best noticed fog harvesting effectivity reached 6.9 g•h⁻¹•cm⁻², demonstrating the potential for sustained and environment friendly fog harvesting even in dynamically altering fog environments. This examine introduces a novel Janus membrane materials that provides broad functions for growing inexperienced, low-cost, and environment friendly fog harvesting methods.
