A simple route is demonstrated to fabricate highly ordered and oriented arrays of PS-b-PEO block copolymer microdomains on inexpensive, flexible polymeric substrates where the lateral ordering is the same as that seen on hard master surfaces. The block copolymer thin films well-developed onto flexible substrates can be used as templates or scaffolds to fabricate a wide range of nanostructured materials for inexpensive, flexible devices.
