在目前的最先进技术中，大多数超级防水表面还不够坚固，无法从实验室进入商业领域。为了创造出可以在更广泛的商业应用中使用的超疏水表面，已经从理论上探索了提高超疏水表面鲁棒性的方法。悬浮压力和液滴保持力进行了研究的粗糙形状，尺寸和间距。这项研究的结果表明，即使在暴露于与液柱或射流相关的大静水压力后，也可以创建保持其液体排斥性的表面。
In the current state-of-the-art, most super repellent surfaces are not sufficiently robust to move out of the laboratory into the commercial realm. With the hope of creating super repellent surfaces that could be employed in a wider variety of commercial applications, means to improve the robustness of ultralyophobic surfaces have been explored theoretically. Suspension pressures and drop retention forces were examined in terms of asperity shape, size, and spacing. The findings from this study suggest a strategy for creating surfaces that maintain their liquid repellency even after exposure to large hydrostatic pressures associated with liquid columns or jets.
