Abstract

Corrosion and ice accretion at low temperatures significantly compromise the operational reliability of facilities and equipment. The development of protective materials that integrate both anti-corrosion and anti-icing properties is crucial for ensuring their safe and sustained service. In this paper, we constructed a novel TiN-loaded photothermal superhydrophobic coating (ZIF-8@PDA@PF-POS@EP-TiN) via a facile spray-coating method for integrated passive anti-icing, active deicing, and anti-corrosion applications. By synergistically incorporating ZIF-8@PDA@PF-POS and TiN into epoxy resin matrix, the coating achieves superhydrophobicity (with water contact angle of 153.1 ± 1.3°, and sliding angle of 1.0 ± 0.1°), exceptional mechanical durability, and efficient photothermal conversion capability under simulated solar irradiation. Electrochemical tests reveal six orders of magnitude higher charge transfer resistance (2.45 × 10¹⁰ Ω cm²) than bare aluminum alloy, indicating superior anti-corrosion performance. Additionally, the coating significantly delays ice formation (15.1 × and 19.7 × longer at −10 °C and −20 °C, respectively) and enables rapid photothermal deicing (complete melting after 393 s at −10 °C and 766 s at −20 °C under 1.0 sun irradiation). This multifunctional superhydrophobic coating offers a robust and energy-efficient anti-corrosion and anti-icing solution for harsh environments such as offshore infrastructure and aerospace systems.

负载锡光热超疏水涂层，具有综合被动防冰、主动除冰和防腐功能

低温下的腐蚀和积冰严重影响了设施和设备的运行可靠性。开发兼具防腐和防冰性能的防护材料对于确保其安全和持续使用至关重要。在本文中，我们通过简单的喷涂方法构建了一种新型的负载tin光热超疏水涂层（ZIF-8@PDA@PF-POS@EP-TiN），用于集成被动防冰、主动除冰和防腐应用。通过将ZIF-8@PDA@PF-POS和TiN协同加入到环氧树脂基体中，涂层具有超疏水性（水接触角为153.1±1.3°，滑动角为1.0±0.1°），优异的机械耐久性以及在模拟太阳照射下的高效光热转换能力。电化学试验结果表明，其电荷转移电阻（2.45×1010 Ω·cm2）比裸铝合金高6个数量级，具有较好的防腐性能。此外，该涂层显著延缓了冰的形成（在-10°C和-20°C时分别延长了15.1倍和19.7倍），并实现了快速光热除冰（在-10°C和-20°C 1.0太阳照射下，在393秒和766秒后完全融化）。这种多功能超疏水涂层为海上基础设施和航空航天系统等恶劣环境提供了坚固、节能的防腐和防冰解决方案。
