Surface modifications are typically permanent in shape and chemistry. Herein, vinylogous urethane (VU) chemistry is presented as an easily accessible and versatile platform for rapid, facile, and reworkable surface modification. It is demonstrated that both physical and chemical post‐modification of permanent, yet dynamic elastic polymer networks are achieved. Surface patterns with high regularity are created, both via a straightforward replication process using a polydimethylsiloxane stamp (resolution ca. 10–100 µm) as well as using thermally activated nano‐imprint lithography (NIL) to form hole, pillar, or line patterns (ca. 300 nm) in elastic VU‐based vitrimers. The tunable, rapid exchange allows patterning at 130 °C in less than 15 min, resulting in an increased water contact angle and surface‐structure induced light reflection. Moreover, it is also demonstrated that the use of a single dynamic covalent chemistry makes it possible to strongly adhere to fluorinated and non‐fluorinated materials based on incompatible matrices, causing cohesive failure in a peel test. In a topography scan, the visibly transparent interface is shown to possess a continuous phase without a gap, while maintaining distinctively separated (non)‐fluorinated domains. Finally, this approach allowed for a straightforward coating of a non‐fluorinated material with a fluorinated monomer to minimize the overall fluorinated content.

通过动态转氨作用对（非）含氟三聚体进行表面改性

表面改性通常在形状和化学上是永久的。本文中，乙烯基氨基甲酸乙酯（VU）化学是一种易于访问的通用平台，可进行快速，便捷和可重做的表面改性。结果表明，永久性的但动态的弹性聚合物网络的物理和化学后修饰都可以实现。通过使用聚二甲基硅氧烷印章（分辨率约10–100 µm）的简单复制过程以及使用热激活的纳米压印光刻（NIL）形成孔，柱或线图案，可以创建具有高规则性的表面图案（约300 nm）在基于VU的弹性微粉中。可调节的快速交换可在不到15分钟的时间内在130°C的温度下形成图案，从而增加了水接触角和表面结构引起的光反射。而且，还证明了使用单一动态共价化学物质可以牢固地粘附到基于不相容基质的氟化和非氟化材料上，从而导致剥离试验中的内聚破坏。在形貌扫描中，可见的透明界面显示出具有不带间隙的连续相，同时保持了明显分开的（非）氟化域。最后，这种方法允许用氟化单体直接涂覆非氟化材料，以最大程度地减少总氟化含量。可见的透明界面显示出具有无间隙的连续相，同时保持了明显分开的（非）氟化域。最后，这种方法允许用氟化单体直接涂覆非氟化材料，以最大程度地减少总氟化含量。可见的透明界面显示出具有无间隙的连续相，同时保持了明显分开的（非）氟化域。最后，这种方法允许用氟化单体直接涂覆非氟化材料，以最大程度地减少总氟化含量。
