Water is one of the most important and crucial indicators of sustainable development goals (SDGs) for humans and other living organisms. Water demand has outstripped supply, resulting in shortage on a worldwide scale, particularly in arid regions. This water scarcity has impeded agricultural productivity and other developmental projects with the ongoing global warming and other anthropogenic activities making it more complicated. To address the worldwide water crisis, it is worthwhile to convert atmospheric air to drinking water. Sequel to that, a hydrophobic surface was designed using facile lithography to compare its water harvesting efficiency with a hydrophilic surface at different orientation angles. For the research, the hydrophobic designed surface is called biodesigned material, while the hydrophilic natural surface is a leaf (MIL). It is against this background that we seek to investigate the most suitable orientation angle good for efficient water harvesting. To that end, a 60° inclination angle is the most efficacious orientation for water collection as it outperformed the 30 and 45° orientation angles. To minimize re-evaporation, absorption, suction, and other environmental challenges that impede efficient collection, atmospheric moisture should be collected immediately from functional surfaces.
水是人类和其他生物可持续发展目标（SDGs）最重要且关键的指标之一。用水需求已超过供给，导致全球范围内水资源短缺，尤其是在干旱地区。随着全球变暖及其他人为活动的持续，这种水资源短缺阻碍了农业生产力及其他发展项目，使其情况更为复杂。为应对全球水危机，将大气中的空气转化为饮用水是值得的。在此之后，通过简易光刻技术设计了一种疏水表面，以比较其与亲水表面在不同取向角度下的集水效率。在这项研究中，设计的疏水表面被称为生物设计材料，而亲水的自然表面是一片叶子（MIL）。正是在这样的背景下，我们试图研究最适合高效集水的取向角度。为此，60°倾斜角是集水最有效的取向，因为它优于30°和45°的取向角度。为尽量减少阻碍高效收集的再蒸发、吸收、吸附及其他环境挑战，应立即从功能表面收集大气中的水分。
