Book excerpt: This dissertation is focused on the characterization of elastomeric block copolymers confined via multilayer co-extrusion technology. In this work, we utilized both self-assembly and forced assembly to achieve hierarchical design within films for mechanical enhancement. When block copolymers are forced to self-assemble in restricted geometries, their physical properties tend to deviate from the bulk behavior. An understanding of their physical properties under confinement has become imperative as technology pushes polymeric applications toward thinner geometries. This work utilizes multilayer co-extrusion as a continuous, confining mechanism to exploit the effect of confining layer and layer thickness on commercially available block copolymers. It was discovered that the morphology and orientation of the block copolymer while under confinement drastically affects the mechanical response of the multilayer films. A thorough understanding of these key factors allows for a methodology to tune the mechanical response of multilayer films via a continuous methodology.
