Abstract

This review provides a comprehensive analysis of materials and methods for creating metallic hydrophobic surfaces and their application in water vapor condensation. It covers various techniques, such as low-energy material coatings, chemical etching, and physical texturing, for developing hydrophobic and superhydrophobic surfaces. The review evaluates physical, chemical, and hybrid approaches, focusing on replicating naturally hydrophobic surfaces and assessing key parameters like equilibrium contact angle, contact angle hysteresis, durability, and scalability. The ideal surface for condensation combines high thermal conductivity, a large equilibrium contact angle, and minimal hysteresis to promote efficient dropwise condensation. Despite significant advancements, challenges remain in the durability and scalability of chemical coatings and in achieving hierarchical roughness similar to lotus leaves. Continued innovation is necessary to improve fabrication methods for broader applications in water vapor condensation.

金属疏水表面：水蒸气凝结的制造方法和应用

本综述全面分析了制造金属疏水表面的材料和方法及其在水蒸气凝结中的应用。它涵盖了开发疏水和超疏水表面的各种技术，如低能材料涂层、化学蚀刻和物理纹理。综述评估了物理、化学和混合方法，重点是复制天然疏水表面和评估平衡接触角、接触角滞后、耐久性和可扩展性等关键参数。理想的冷凝表面应兼具高导热性、大平衡接触角和最小滞后性，以促进高效的液滴冷凝。尽管取得了重大进展，但在化学涂层的耐久性和可扩展性以及实现类似荷叶的分层粗糙度方面仍然存在挑战。有必要继续创新，改进制造方法，以更广泛地应用于水蒸气冷凝。

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
