A single, conventional poly(dimethylsiloxane) (PDMS) stamp is used under a dynamic microcontact printing (uCP) method, extended from a static one. This new approach is investigated and combined with surface-initiated atom-transfer radical polymerization
(SI-ATRP) to fabricate complex patterned hierarchical and gradient polymer-brush
microstructures with a number of different feature morphologies that do not exist on
the original stamp without sophisticated instrumentation being necessary.
