Substrate patterning using regular macroporous block copolymer monoliths as sacrificial templates and as capillary microstamps

Leiming Guo, Michael Philippi, Martin Steinhart

Polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) monoliths containing regular arrays of macropores (diameter ~1.1 microns, depth ~700 nm) at their surfaces are used to pattern s…
