论文摘要
以前的理论著作表明，可以通过部分抑制宽带 - 吸收器超材料的表面上的量子真空模式来增强超疏水性，从而在极端的紫外线频域中起作用。然后，这种效果将与经典的卡西 - 巴克斯特对超疏水性的解释进行竞争。在本文中，我们首先在理论上建立了与这种“量子”超疏水性相关的预期现象学特征。然后，依靠这个理论框架，我们在实验上研究了有机硅烷分子移植的图案硅表面，所有涂层表面具有相似的特征模式大小但曲线不同。这些表面中的一些确实可以冻结量子光子模式，而另一些则不能。虽然后者允许疏水性，但只有前者才能具有超疏水性。我们认为，这些结果为进一步评估量子波动引起的超级疏水性奠定了基础。
Previous theoretical works suggested that superhydrophobicity could be enhanced through partial inhibition of the quantum vacuum modes at the surface of a broadband-absorber metamaterial which acts in the extreme ultraviolet frequency domain. This effect would then compete with the classical Cassie-Baxter interpretation of superhydrophobicity. In this article, we first theoretically establish the expected phenomenological features related to such a kind of "quantum" superhydrophobicity. Then, relying on this theoretical framework, we experimentally study patterned silicon surfaces on which organosilane molecules were grafted, all the coated surfaces having similar characteristic pattern sizes but different profiles. Some of these surfaces can indeed freeze quantum photon modes while others cannot. While the latter ones allow hydrophobicity, only the former ones allow for superhydrophobicity. We believe these results lay the groundwork for further complete assessment of superhydrophobicity induced by quantum fluctuations freezing.
