Abstract：
Slippery liquid-infused porous surfaces (SLIPS) have received widespread attention in the antifouling field. However, the reduction in antifouling performance caused by lubricant loss limits their application in marine antifouling. Herein, inspired by the skin of a poison dart frog which contains venom glands and mucus, a porous liquid (PL) based on ZIF-8 is prepared as a lubricant and injected into a silicone polyurethane (SPU) matrix to construct a new type of SLIPS for marine antifouling applications: the slippery porous-liquid-infused porous surface (SPIPS). The SPIPS consists of a responsive antifoulant-releasing switch between \"defensive\" and \"offensive\" antifouling modes to intelligently enhance the antifouling effect after lubricant loss. The SPIPS can adjust antifouling performance to meet the antifouling requirements under different light conditions. The wastage of antifoulants is reduced, thereby effectively maintaining the durability and service life of SLIPS materials. The SPIPS exhibits efficient lubricant self-replenishment, self-cleaning, anti-protein, anti-bacterial, anti-algal, and self-healing (97.48%) properties. Furthermore, it shows satisfactory 360-day antifouling performance in actual marine fields during boom seasons, demonstrating the longest antifouling lifespan in the field tests of reported SLIPS coatings. Hence, the SPIPS can effectively promote the development of SLIPS for neritic antifouling.
摘要：
滑液多孔表面(SLIPS)在防污领域受到广泛关注。然而,润滑剂损失导致的防污性能降低限制了它们在海洋防污中的应用。在这里，灵感来自含有毒腺和粘液的毒镖青蛙的皮肤，制备基于ZIF-8的多孔液体（PL）作为润滑剂，并注入有机硅聚氨酯基质中，以构建用于海洋防污应用的新型SLIPS：光滑的多孔液体注入多孔表面（SPIPS）。SPIPS包括“防御性”和“进攻性”防污模式之间的响应性防污剂释放开关，以智能地增强润滑剂损失后的防污效果。SPIPS可以调节防污性能，以满足不同光照条件下的防污要求。减少了防污剂的浪费,从而有效保持SLIPS材料的耐久性和使用寿命。SPIPS表现出有效的润滑剂自我补充，自我清洁,抗蛋白质，抗菌,抗藻,和自我修复(97.48%)性能。此外，它在繁荣季节的实际海洋领域显示出令人满意的360天防污性能，在报告的SLIPS涂层的现场测试中证明了最长的防污寿命。因此，SPIPS可以有效促进SLIPS的发展。本文受版权保护。保留所有权利。
