Super non-wetting surfaces are considered the optimal surface for applications as varied as shower walls, windshields, turbine blades, etc. While research interest in this field is huge, surfaces that behave non-wetting to any fluid (superomniphobic) are still largely sought after in industrial applications, which can be explained by two reasons: (1) many of the presented fabrication techniques are not suitable for large area applications, require multiple expensive fabrication steps or are based on environmentally harmful coatings, which are readily damaged and require reapplication; (2) many of the presented surfaces behave non-wetting under ideal laboratory conditions, but fail in real applications.

超级非润湿表面被认为是各种应用的最佳表面，如淋浴墙、挡风玻璃、涡轮机叶片等。虽然在该领域的研究兴趣很大，但对任何流体都不润湿的表面（超全憎）在工业应用中仍然很大程度上受到追捧，这可以由两个原因解释：（1）所提出的许多制造技术不适合于大面积应用，需要多个昂贵的制造步骤或基于容易损坏并需要重新施加的对环境有害的涂层;（2）许多提出的表面在理想的实验室条件下表现为非润湿性，但在真实的应用中失败。
