多孔玻璃瓷砖已经与低表面能涂层反应，产生疏水表面。用表面活性剂清洗表面可降低疏水性，润湿状态由Cassie-Baxter变为Wenzel。当空气通过浸入水中的多孔玻璃时，会形成固-气-液界面，这与疏水性的恢复有关。报道了具有这种效应的微孔玻璃的加工和显微结构特征。潜在的应用包括低摩擦管道，在水-管道界面保持卡西-巴克斯特状态将显著减少输送水所需的能量。
Porous glass tiles have been reacted with a low-surface energy coating to produce hydrophobic surfaces. Washing the surface with surfactant reduces hydrophobicity and the wetting state changes from Cassie-Baxter to Wenzel. Passing air through the porous glass when it is immersed in water causes a solid-gas-liquid interface to form and this is associated with recovery of hydrophobicity. The processing and microstructural characteristics of the porous glass that show this effect are reported. Potential applications include low-friction pipes, where maintaining the Cassie-Baxter state at the water-pipe interface would significantly reduce the energy required to transport water.
