Polydopamine coating is a unique, simple, and substrate-independent surface functionalization strategy. Techniques for secondary functionalization, patterning, and re-functionalization of polydopamine modified materials are important to broaden the scope of applications of such materials in a variety of fields. Here, a facile and substrate-independent strategy for surface functionalization and patterning is presented. This approach combines the advantages of three important methods: facile and substrate-independent polydopamine coating, versatile gas phase silanization, and rapid thiol-ene photoclick reaction for patterning. They demonstrate equally efficient functionalization and patterning of diverse materials, such as glass, polytetrafluoroethylene, aluminum, polypropylene, or polyethylene. They also show the possibility of controlled chemical removal of the patterns or surface functionalization by treatment with tetrabutylammonium fluoride, which allows re-modification or re-patterning of the substrate. Thus, this universal and powerful approach for substrate independent surface modification and patterning can significantly facilitate the development of novel functional materials and devices useful for various applications.

通过结合聚多巴胺涂层、硅烷化和硫醇 - 烯反应实现与基材无关且可重写的表面图案

聚多巴胺涂层是一种独特、简单且与基材无关的表面功能化策略。聚多巴胺改性材料的二次功能化、图案化和再功能化技术对于拓宽此类材料在各个领域的应用范围很重要。在这里，提出了一种用于表面功能化和图案化的简便且独立于基材的策略。这种方法结合了三种重要方法的优点：简便且独立于基材的聚多巴胺涂层、多功能气相硅烷化和用于图案化的快速硫醇-烯光点击反应。它们展示了对不同材料（例如玻璃、聚四氟乙烯、铝、聚丙烯或聚乙烯）的同样有效的功能化和图案化。它们还显示了通过用四丁基氟化铵处理来控制化学去除图案或表面功能化的可能性，这允许对基材进行重新修饰或重新图案化。因此，这种通用且强大的基板独立表面改性和图案化方法可以显着促进可用于各种应用的新型功能材料和器件的开发。
