标题： Suppression of water vapor condensation by glycerol droplets on hydrophobic surfaces

摘要： 蒸汽吸收器是一种有效抑制亲水材料周围水蒸气冷凝形成的战略，从而减少结霜和结冰。 然而，传统使用的材料，如盐溶液、纤维，表现出冷凝抑制不足或存在安全问题，如腐蚀性。 在本研究中，我们强调了甘油液滴的显著抗冷凝特性，这归因于其强吸湿性。 我们比较了甘油液滴与常用盐溶液和亲水醇的抗冷凝能力。 结果表明，甘油液滴建立了一个相对广阔的干燥区域，有效抑制冷凝，同时相比其他材料也提供了安全性。 此外，我们通过实验和理论分析对甘油液滴的抗冷凝特性进行了系统研究。 我们探讨了在疏水表面上，干燥区域比例随温度、冷却时间、湿度和液滴体积的变化趋势。 为了提供全面的理解，我们提出一个简单而稳健的理论模型，解释了该比例与温度之间的关系，并与实验数据高度吻合。 我们的研究不仅揭示了甘油卓越的抗冷凝特性，还为开发有效的抗冰和抗霜材料提供了见解和指导。 显示英文摘要

摘要： Vapor sink is an effective strategy to suppress the formation of water vapor condensation around hygroscopic materials, and consequently reduce frosting and icing. However, traditionally used materials, such as salt solutions, fibers, exhibit insufficient condensation inhibition or pose safety concerns, such as corrosiveness. In this study, we highlight the remarkable anti-condensation properties of glycerol droplets, attributed to their strong hygroscopicity. We compared the anti-condensation capabilities of glycerol droplets with commonly used salt solutions and hygroscopic alcohols. The results indicated that glycerol droplets establish a relatively expansive dry zone where the condensation is effectively inhibited, while also offering safety compared to other materials. Furthermore, we conducted a systematic study of the anti-condensation properties of glycerol droplets with experiments and theoretical analysis. We explored the varying trends of the dry zone ratio concerning temperature, cooling time, humidity, and droplet volume on hydrophobic surfaces. To provide a comprehensive understanding, we propose a straightforward yet robust theoretical model that elucidates the relationship between this ratio and temperature, aligning well with the experimental data. Our study not only sheds light on the superior anti-condensation qualities of glycerol but also offers insights and guidelines for the development of effective anti-icing and anti-frost materials.
