滑爽的液体注入多孔表面(SLIPS)具有巨大的潜力,以取代传统的防污涂料,绿色,和广谱防污性能。然而,SLIPS的润滑油耗散问题严重制约了SLIPS的进一步发展和应用,强大的SLIPS仍然极具挑战性。这里,由石蜡组成的复合相变润滑剂层,硅油,和MXene被设计成容易地构建稳定和NIR响应的自修复相变固体光滑表面(PCSSS)。结果表明,PCSSS在近红外辐射下能够快速实现相变,完成自愈,并在高速水冲洗后保持稳定。离心,和超声波治疗。通过蛋白质评估PCSSS的防污性能,细菌,藻类抗粘附试验表明,粘附抑制率高达99.99%。此外,EIS和动电位极化实验表明,PCSSS具有稳定且出色的耐腐蚀性(|Z|0.01Hz=3.87×108Ω·cm2),可以有效抑制微生物腐蚀。90天的实际海洋测试表明,PCSSS具有显着的防污性能。因此,PCSSS提出了一种新颖的,轻而易举,和构建光滑表面的有效策略,有望促进其在海洋防污和腐蚀防护中的应用。
Slippery liquid-infused porous surfaces (SLIPSs) have great potential to replace traditional antifouling coatings due to their efficient, green, and broad-spectrum antifouling performance. However, the lubricant dissipation problem of SLIPS severely restricts its further development and application, and the robust SLIPS continues to be extremely challenging. Here, a composite phase-change lubricant layer consisting of paraffin, silicone oil, and MXene is designed to readily construct a stable and NIR-responsive self-healing phase-change solid slippery surface (PCSSS). Collective results showed that PCSSS could rapidly achieve phase-change transformation and complete self-healing under NIR irradiation and keep stable after high-speed water flushing, centrifugation, and ultrasonic treatment. The antifouling performance of PCSSS evaluated by protein, bacteria, and algae antiadhesion tests demonstrated the adhesion inhibition rate was as high as 99.99%. Moreover, the EIS and potentiodynamic polarization experiments indicated that PCSSS had stable and exceptional corrosion resistance (|Z|0.01Hz = 3.87 × 108 Ω·cm2) and could effectively inhibit microbiologically influenced corrosion. The 90 day actual marine test reveals that PCSSS has remarkable antifouling performance. Therefore, PCSSS presents a novel, facile, and effective strategy to construct a slippery surface with the prospect of facilitating its application in marine antifouling and corrosion protection.
