Slippery-liquid-infused porous surfaces (SLIPS) are state-of-the-art materials owing to their excellent properties derived from their fluidity (e.g., dynamic omniphobicity and self-healing function). Although SLIPS have been multifunctionalized and developed for various applications, the fabrication process is not well advanced because it is time-consuming and requires multiple steps. Here, a versatile method is reported for the instant formation of slippery surfaces in situ. A lubricated fiber-filled porous sheet was designed, and a coating was formed simply by sticking a surface to the sheet. This sheet can be used as a "disposable instant coating kit" and be made available for instant and repeated coating of SLIPS. The technique is applied to a transparent antifouling endoscope lens as a proof-of-concept. This work improves the fabrication process of SLIPS and contributes to the practical use of SLIPS.
注入滑液的多孔表面（SLIPS）因其流动性带来的优异性能（如动态全憎性和自愈功能）而成为先进材料。尽管SLIPS已实现多功能化并开发用于各种应用，但其制造工艺进展不佳，因为耗时且需要多个步骤。在此，报道了一种用于原位即时形成光滑表面的通用方法。设计了一种填充有润滑纤维的多孔片材，通过将表面粘贴到该片材上即可简单地形成涂层。该片材可作为“一次性即时涂层套件”，用于即时和重复涂覆SLIPS。该技术作为概念验证应用于透明防污内窥镜镜头。这项工作改进了SLIPS的制造工艺，并有助于SLIPS的实际应用。
