Abstract: Permeation across thin films can be retarded when the films contain aligned flakes of a less permeable material, but aligning these flakes can be difficult. In this research, we measure transport across less permeable flakes which self-assemble from a triblock copolymer. Elasticity is most influenced by an isoprene block but permeability is dominated by a lactide block. The permeability of this lamellar composite for helium, oxygen, and nitrogen is about 20
