Surface Patterning Using Microchannel-Confined Surface Transformation ( ST)



Chang Xu, Kathryn L. Beers


Most surface patterned polymer brushes synthesized to date contain only one type of polymer and the remaining surface areas are either bare substrate or SAM. To further control the entire surface area, several methods have been developed to fabricate surfaces with binary polymer brushes, two distinct polymer brushes which form and cover the whole patterned surface. In this work, we introduce microchannel-confined surface transformation ( ST), a technique that explores reactions under the confinement of microfluidic channels comprised of elastomer stamps and surfaces to pattern the surfaces with different chemistries at nanoscale resolution. We applied this technique to pattern surfaces with different initiator functionalities, from which surface-initiated polymerizations resulted in patterned binary polymer brushes.
