Abstract

The objective of this study is to develop a practical superhydrophobic coating with sustainable and robust superhydrophobic properties. Inspired by the natural self-repairing ability and sustainability in biological tissues, this objective was achieved by combining the self-repairing properties of proteins with the robustness of tendons into the fabrication of superhydrophobic coatings. To the end, the superhydrophobic coating was developed in the proposed form in which waterborne polyurethane was adopted to provide the protein-like self-repairing properties and the tendon-like robustness due to the bio-like and comparable composition. The result showed that the prepared coating possessed the desired sustainable and robust superhydrophobic properties, with the contact angle of up to 156.4° and the rolling angle of 4.6° The damage in the superhydrophobic properties of this coating, due to the erosion from a strong acid, can be reinstated with heating. The self-repairing-reinforcing sustainability and robustness reinforced the durability and the wear and corrosion resistance. This work shares a prospect with developing sophisticated coatings for applications and in particular practical applications.

具有自我修复增强可持续性和坚固性的仿生超疏水涂层的开发

本研究的目的是开发一种具有可持续和坚固的超疏水性能的实用超疏水涂层。受生物组织的自然自我修复能力和可持续性的启发，这一目标是通过将蛋白质的自我修复特性与肌腱的坚固性结合到超疏水涂层的制造中来实现的。最后，以所提出的形式开发了超疏水涂层，其中采用水性聚氨酯提供类似蛋白质的自修复性能和类似肌腱的坚固性，这是由于类似生物和可比的成分。结果表明，制备的涂层具有良好的超疏水性能，接触角可达156.4°，滚转角可达4.6°，且由于强酸的侵蚀，涂层的超疏水性能可通过加热恢复。自我修复增强的可持续性和坚固性增强了耐久性和耐磨损和耐腐蚀性。这项工作与开发用于应用和特别是实际应用的复杂涂层具有共同的前景。

期刊介绍： Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials. Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
