A facile approach to unique 3D, patterned polymer brushes is based on visible‐light‐mediated controlled radical polymerization. The temporal and spatial control of the polymerization allows the patterning of polymer brushes from a uniform initiating layer using a simple photomask (see picture). Furthermore, gradient polymer brushes, patterned block copolymers, and complex 3D structures can be obtained
独特的3D图案化聚合物笔刷的简便方法是基于可见光介导的受控自由基聚合。聚合的时间和空间控制允许使用简单的光掩模从均匀的引发层对聚合物刷进行构图(参见图片)。此外,可以通过调节光强度来获得渐变聚合物刷,带图案的嵌段共聚物和复杂的3D结构。
