Covalently attached liquids provide a liquid–liquid surface interaction for contacting contaminants, typically achieved through use of a polydimethylsiloxane linear polymer bound to the surface at one end. The attached dimethylsiloxane polymer chain retains liquid‐like mobility through bending and rotational motions, distinguishing the coatings from those formed by crosslinked polydimethylsiloxane or branched polymer chains. Here, covalently attached liquids are reviewed and their potential for application as topcoat treatments is discussed. This review focuses on a new use scenario: prevention of chemical contamination. When allowed to age in place, chemical contaminants tend to penetrate into painted surfaces. Standard decontamination processes can fail to remove the chemicals within the paint layer, resulting in secondary exposure hazards when environmental conditions change. Covalent liquid coatings provide repellency and shedding behaviors. This review highlights the failure of typical wetting evaluations in predicting performance for the new application as well as the potential of the coatings in enhancing chemical resistance for painted surfaces. Potential methods for further improvements are also discussed. Published 2020. This article is a U.S. Government work and is in the public domain in the USA

共价附着的液体作为保护涂层

共价结合的液体为接触污染物提供液-液表面相互作用，通常是通过使用一端结合到表面的聚二甲基硅氧烷线性聚合物来实现的。附着的二甲基硅氧烷聚合物链通过弯曲和旋转运动保留了液体状的流动性，从而将涂层与交联的聚二甲基硅氧烷或支链聚合物链形成的涂层区分开来。在此，对共价连接的液体进行了综述，并讨论了其作为面漆处理剂的应用潜力。此次审查的重点是新的使用场景：防止化学污染。当放置在适当的位置时，化学污染物往往会渗入涂漆的表面。标准的去污工艺可能无法去除漆层内的化学物质，当环境条件发生变化时，会导致二次接触危害。共价液体涂料可提供排斥和脱落行为。这篇综述强调了典型的润湿评估在预测新应用性能方面的失败以及涂料在增强涂漆表面的耐化学性方面的潜力。还讨论了进一步改进的潜在方法。出版于2020年。本文是美国政府的工作，在美国属于公共领域 还讨论了进一步改进的潜在方法。出版于2020年。本文是美国政府的工作，在美国属于公共领域 还讨论了进一步改进的潜在方法。出版于2020年。本文是美国政府的工作，在美国属于公共领域
