The orientation of microdomains in block copolymer thin films is controlled by two simple strategies that have been developed through controlling interfacial interactions by anchoring end-functionalized polymers to the substrate. Combined with solvent annealing, these methods provide a simple route for manipulating the orientation and lateral order of the copolymer microdomains.
