Multiplex Biomimetic SLIPS With Super‐Lubricity to Multiphase Matters

In recent years, slippery liquid infused porous surfaces (SLIPS) renowned for their exceptional liquid repellency and anti-fouling properties, have garnered considerable attention. However, the instability of both structural integrity and the oil film severely restricts their practical applications. This study is inspired by superwetting biological surfaces, such as fish scales, seashells, and Nepenthes, to design and fabricate a multiplex biomimetic and robust lubricant-infused textured surface (LITMS) using laser-coating composite processing technology. The influence of morphological structure and chemical composition on oil stability, wettability, and lubricating properties are systematically investigated. The LITMS exhibits remarkable repellency toward multiphase materials, including liquids, ice crystals, and solids, demonstrating exceptional omniphobicity, anti-icing, and anti-friction properties. Thus, this preparation strategy and construction methodology for SLIPS provide new insights into interfacial phenomena and promote advancements in applications for engineering material protection and machinery lubrication.
