Multifunctional Micro/Nanostructured Interfaces, Fabrication Technologies, Wetting Control, and Future Prospects

Abstract Recent advances in micro/nanostructured surfaces have facilitated the development of multifunctional materials with remarkable liquid repellency, anti‐fouling, particle capture, and electronic performances. Inspired by natural surfaces such as lotus leaves and springtail arthropod skin, these engineered interfaces employ hierarchical and reentrant geometries to regulate wetting behavior and interfacial energy. This review summarizes recent progress in the scalable fabrication of complex surface architectures, focusing on techniques such as UV nanoimprint lithography, digital light processing, and roll‐to‐roll imprinting. These approaches, often combined with advanced process innovations such as oxygen‐inhibited curing and mold tiling, have demonstrated the capability to fabricate precise large‐area microstructures with high throughput. Applications in superomniphobic, anti‐icing, anti‐microbial, and biomimetic replicas are highlighted, demonstrating both laboratory breakthroughs and industrial potential. Finally, the review addresses key challenges such as scalability, durability, and sustainability, and proposes future directions that integrate computational modeling. This review serves as a practical guide for researchers and engineers in the design and implementation of next‐generation functional surfaces.
