Liquefaction of vapor is a necessary, but energy intensive step in several important process industries. This review identifies possible materials and surface structures for promoting dropwise condensation, known to increase efficiency of condensation heat transfer. Research on superhydrophobic and superomniphobic surfaces promoting dropwise condensation constitutes the basis of the review. In extension of this, knowledge is extrapolated to condensation of CO₂. Global emissions of CO₂ need to be minimized in order to reduce global warming, and liquefaction of CO₂ is a necessary step in some carbon capture, transport and storage (CCS) technologies. The review is divided into three main parts: 1) An overview of recent research on superhydrophobicity and promotion of dropwise condensation of water, 2) An overview of recent research on superomniphobicity and dropwise condensation of low surface tension substances, and 3) Suggested materials and surface structures for dropwise CO₂ condensation based on the two first parts.

在一些重要的过程工业中，蒸气的液化是必需的，但会消耗大量能量。这篇综述指出了促进滴状冷凝的可能的材料和表面结构，已知这些材料和表面结构可提高冷凝传热的效率。超疏水和超疏水表面促进逐滴凝结的研究构成了本综述的基础。此外，知识被推断为CO _2的缩合。为了减少全球变暖和CO _2的液化，需要使CO _2的全球排放最小化。是某些碳捕集，运输和封存（CCS）技术的必要步骤。这篇综述分为三个主要部分：1）关于超疏水性和促进水的逐滴缩合的最新研究概述； 2）关于低表面张力物质的超疏水性和逐滴缩合的最新研究概述； 3）建议的材料和基于两个第一部分的用于CO ₂逐滴冷凝的表面结构。
