19世纪世纪，奥斯卡·王尔德说：“我很遗憾地说，我们生活在一个表面的时代。今天，我们做得更多，我们并不后悔：在理解和制造具有可控润湿性能的表面方面的关键进展即将使无污染（或“免清洗”）表面的梦想成真。两种自清洁的途径正在出现，它们通过薄膜或液滴流动去除污垢来工作。虽然详细了解液体在这种表面上的行为的机制仍然是一个基本的研究课题，但家用商品部门和生物技术应用的第一批商业产品即将进入市场。这份进展报告描述了对基本机制的理解的现状，制作这种表面的概念，以及它们的一些初步应用。
In the 19th century, Oscar Wilde stated “We live, I regret to say, in an age of surfaces”. Today, we do so even more, and we do not regret it: key advances in the understanding and fabrication of surfaces with controlled wetting properties are about to make the dream of a contamination-free (or 'no-clean') surface come true. Two routes to self-cleaning are emerging, which work by the removal of dirt by either film or droplet flow. Although a detailed understanding of the mechanisms underlying the behaviour of liquids on such surfaces is still a basic research topic, the first commercial products in the household-commodity sector and for applications in biotechnology are coming within reach of the marketplace. This progress report describes the current status of understanding of the underlying mechanisms, the concepts for making such surfaces, and some of their first applications.
