Fabrication of micro- and nanostructures at line-speed of 60 m min−1 by large-area roll-to-roll extrusion coating is demonstrated. Nanopillars with diameters 80 nm and heights 100 nm are replicated in polypropylene. The main limiting factor for replication on nanoscale is the retardation time for solidification of the melt.
