Polymer brush-assisted microcontact printing: using a tailor-made polydimethylsiloxane (PDMS) stamp for precise patterning of rough surfaces

Abstract

We present a PDMS-based stamp featuring xanthates within its framework, to graft polymer brushes from its surface. The stamp demonstrates a high efficacy of polymer-supported μCP, but does not show leakage of oligomeric PDMS, which represents a common source of contamination in soft lithography.
