Superamphiphobic surfaces, capable of repelling both water and oil, have been extensively studied recently. Artificial superamphiphobic surfaces with ultralow solid/liquid adhesion and high transparency have been achieved separately. However, simultaneous demonstration of these two features remains a challenge. Here, we designed a superamphiphobic surface possessing a re-entrant curvature on both nano- and microscales uniformly, each maintaining their capabilities. The achieved micro/nano re-entrant-coordinated superamphiphobic surface performed ultralow solid/liquid adhesion for liquids with high viscosities or low surface tension and showed excellent transparency. This rationally designed model of the superamphiphobic surface may provide useful guidelines for fabrication of superamphiphobic surfaces and enable potential applications ranging from self-cleaning materials to optical devices, such as solar panels, wind screens, and goggles.
超双疏表面能够同时排斥水和油，近年来受到了广泛研究。分别制备出了具有超低固液粘附力和高透明度的人工超双疏表面。然而，同时展现出这两种特性仍然是一项挑战。在此，我们设计了一种在纳米和微米尺度上均具有向内凹曲率的超双疏表面，且各自保持其功能。所制备的微/纳米向内凹协同超双疏表面对高粘度或低表面张力液体表现出超低固液粘附力，并具有优异的透明度。这种经过合理设计的超双疏表面模型可能为超双疏表面的制备提供有用的指导方针，并实现从自清洁材料到光学器件（如太阳能板、挡风玻璃和护目镜）等潜在应用。
