The image illustrates dynamic printing using a conventional PDMS stamp by moving or jumping the stamp during microcontact printing (μCP). This new strategy, denoted “dynamic μCP”, could be combined with SI‐ATRP to fabricate new, complex (hierarchical and gradient) polymer‐brush microstructures with a number of feature morphologies that do not exist on the original stamp. The advantage lies in being able to pattern a series of complex polymer‐brush microstructures using a single stamp without sophisticated instrumentation. This allows the various printing conditions for the transfer of thiols onto metallic surfaces to be systematically established, and, further, it provides a point of departure to micro/nanofabrication applied not only to pattern polymer brushes, but also to other fields, such as selective wet etching or the deposition of different materials.
