最近，人们对接触角、润湿表面和非润湿表面产生了极大的兴趣，近年来发表的论文数量之多和速度之快证明了这一点。然而，在许多情况下，存在对术语的误解和误用，导致对实验接触角的误解，其测量看起来似乎很简单。描述接触角、润湿性、超疏水性和类似其他术语的术语使用得很松散。在这份贡献中，与接触角有关的关键术语是基于过去几十年来表面化学界积累的知识而精确定义的。所提供的定义在科学上是严格的，以避免任何歧义和混淆。这些定义背后的理论考虑仅被简要提及，并参考了相关论文。如果清楚地理解基本概念并应用基于理论的指示，则可以使测量的接触角的解释和意义变得更简单。定义的清晰度应该会使数据解释和比较更容易，以便今后对期刊，包括本期刊的投稿。
Much interest has recently been focused on contact angles, wetting and non-wettable surfaces as is evidenced by the rapid pace and sheer number of papers published in recent years. However, in many cases there exist misconceptions and misuses of terminology, leading to misinterpretation of experimental contact angles, measurements of which deceptively appear to be simple. Terms describing contact angles, wettability, superhydrophobicity and similar other terminology are loosely used. In this contribution, key terms used in relation to contact angles are defined precisely based on the accumulative knowledge from the surface chemistry community over the last decades. The definitions provided are scientifically rigorous to avoid any ambiguity and confusion. The theoretical considerations underlying these definitions are only briefly mentioned, with references to the relevant papers. Interpretation and meaning of the measured contact angles can be made simpler if the basic concepts are clearly understood and theory-based indications are applied. The clarity of definitions should make data interpretation and comparison easier for future contributions to journals, including this journal.
