A spherical, block copolymer (BCP) with a statistical mid-block was investigated under confinement via forced assembly co-extrusion. This approach provided a continuous methodology to investigate the effect of layer thickness and substrate on the morphology of a unique self-assembling material. It was demonstrated that substrate interactions and layer thickness can promote long-range ordering for use in highly diverse nanotechnology applications.
