摘要

受人体牙釉质分层结构的启发，开发了一种具有弹性梯度的超疏水涂层，并将其放置在输气管道内壁上，以减少侵蚀和腐蚀。涂层包括坚硬的仿生超疏水涂层和用于缓冲和自我修复的水凝胶层。通过控制月桂酸（LA）@TiO2粒子和碳纳米管（CNTs）的含量，构建了具有不同粘弹性的层状结构，提高了涂层的抗冲击性能。底层的直链淀粉水凝胶不仅可以起到减震器的作用，还可以修复表层的潜在损伤，从而为涂层的耐腐蚀性带来额外的好处。由于这三种合作方法，涂层具有优异的机械耐久性（在49 kPa载荷下使用600网砂纸进行800次循环）和耐腐蚀性（腐蚀电位为- 0.21 V）。此外，在打磨、弯曲、浸泡和刮擦后，它仍保持超疏水性，这表明了它在保护输电管道免受侵蚀和腐蚀方面的应用潜力。

A Biomimetically Constructed Superhydrophobic Coating with Excellent Mechanical Durability and Chemical Stability for Gas Transmission Pipelines

Inspired by the layered structure of dental enamel in the human body, a superhydrophobic coating with an elastic gradient was developed and placed on the inner wall of a gas transmission pipeline to reduce erosion and corrosion. The coating comprises a hard bionic superhydrophobic top coating and a hydrogel layer underneath for buffering and self-repair. To improve the impact resistance of the top coating, layered structures with different viscoelasticities were constructed by controlling the content of lauric acid (LA)@TiO₂ particles and carbon nanotubes (CNTs). The amylose hydrogel underlayer not only acts as a shock absorber but also restores potential damage in the top layer, bringing an additional benefit to the corrosion resistance of the coating. Thanks to these three cooperative approaches, the coating exhibits excellent mechanical durability (800 cycles with 600-mesh sandpaper under a 49 kPa load) and corrosion resistance (with a corrosion potential of −0.21 V). Moreover, it maintains its superhydrophobicity after sanding, bending, soaking, and scratching, demonstrating its potential for application to protect transmission pipelines from erosion and corrosion.
