Bioinspired superwettable surfaces have been widely harnessed in diverse applications such as self-cleaning, oil/water separation, and liquid transport. So far, only a little work is focused on scalephobic capability of those superwettable surfaces. However, the troublesome scale deposition will inevitably be observed in our daily production and life, greatly reducing heat transfer efficiency and inhibiting the liquid transport. To address this annoying problem, as the emerging strategy, specific barrier layers are introduced onto superwettable surfaces to reduce or even avoid the direct contact between scale and the surfaces. In this feature article, we first provide the basic concept of bioinspired scalephobic surfaces with specific barrier layers. Then, we briefly introduce the typical fabrication methods of scalephobic surfaces. Later, we summarize recent progress of bioinspired scalephobic surfaces with specific barrier layers. Furthermore, we point out the guiding theory and criteria for the stability of barrier layers. Finally, we put forward the forecast on the existing problems and future direction in bioinspired scalephobic surfaces.
受生物启发的超润湿表面在自清洁、油水分离和液体输送等多种应用中得到了广泛的利用。到目前为止，只有很少的工作集中在那些超润湿表面的疏冰能力上。然而，在我们的日常生产和生活中，不可避免地会出现令人讨厌的结垢现象，这大大降低了传热效率，并抑制了液体的输送。为了解决这个令人烦恼的问题，作为一种新兴的策略，在超润湿表面上引入了特定的阻挡层，以减少甚至避免结垢与表面的直接接触。在这篇专题文章中，我们首先提供了具有特定阻挡层的仿生疏冰表面的基本概念。然后，我们简要介绍了疏冰表面的典型制备方法。随后，我们总结了具有特定阻挡层的仿生疏冰表面的最新进展。此外，我们指出了阻挡层稳定性的指导理论和标准。最后，我们对仿生疏冰表面存在的问题和未来的发展方向提出了预测。
