Flow can transfer the microphase separated morphology of block copolymers into a state of global order. For tri-block copolymers with cylindrical domains, this has been demonstrated by Folkes et al. (1973) and Hadziioannou et al. (1979). who established the existence of ‘single crystals’ of hexagonally ordered cylinders with uniform director throughout a sheared sample. The director is aligned with the shear direction. In this study, we investigate the flow induced ordering of cylindrical domain structure at increasing levels of shear.
