Gas bubbles in aqueous media are common and inevitable in, for example, agriculture and industrial processes. The behaviors of gas bubbles on solid interfaces, including generation, growth, coalescence, release, transport, and collection, are crucial to gas‐bubble‐related applications, which are always determined by gas‐bubble wettability on solid interfaces. Here, the recent progress regarding the study of interfaces with gas‐bubble superwettability in aqueous media, i.e., superaerophilicity and superaerophobicity, is summarized. Some examples illustrate how to design microstructures and chemical compositions to achieve reliable and effective manipulation of gas‐bubble wettability on artificial interfaces. These designed interfaces exhibit excellent performance in gas‐evolution reactions, gas‐adsorption reactions, and directional gas‐bubble transportation. Moreover, progress in the theoretical investigation of gas‐bubble superwettability is reported. Lastly, some challenges are presented, such as the reliable manipulation of gas‐bubble wettability and the establishment of mature theory for exactly and systematically explaining gas‐bubble wetting phenomena.

气泡的超润湿性及其应用：从生物启发到先进材料

在例如农业和工业过程中，水性介质中的气泡是常见且不可避免的。气泡在固体界面上的行为，包括生成，生长，聚结，释放，传输和收集，对于气泡相关的应用至关重要，而气泡相关的应用始终取决于气泡在固体界面上的润湿性。在此，总结了有关与水性介质中气泡超润湿性（即超好氧性和超好氧性）的界面研究的最新进展。一些例子说明了如何设计微观结构和化学成分，以实现对人造界面上气泡润湿性的可靠而有效的控制。这些设计的界面在气体逸出反应，气体吸附反应，和定向气泡运输。此外，据报道在气泡超湿性的理论研究方面取得了进展。最后，提出了一些挑战，例如对气泡润湿性的可靠控制以及建立准确，系统地解释气泡润湿现象的成熟理论。
