| Abstract Scope |
Fresh water resources that human can directly use account for only 0.26% of the total water on earth. Capturing water vapor in the air could be an eco-friendly and sustainable solution. Researchers have conceived the unique structures of sisal (Agave sisalana) and fabricated nano-needle arrays on substrates for water collection. In this study, we proposed a facile, rapid, low-cost, and low-energy-consuming method to fabricate sisal-inspired multilevel structures with hydrophilic and hydrophobic surfaces that captured and collected fog efficiently by 3D-printing patterned samples with resin materials. Results showed that the sisal-inspired structures can collect more fog (3.26 g/hr) than the flat substrate (1.47 g/hr). To enhance the fog collection efficiency, the spray coating method was applied to form micrometer-scale protrusions. Surface morphology and microstructural features were characterized by scanning laser confocal microscopy and SEM. This efficient and facile approach can be further applied to fog harvesting, wettable surfaces and micro-fluidic devices. |
