Ionic conductivity in a lamellar diblock copolymer system. (a) Limiting cases of lamellar alignment and orientation with respect to electrode surfaces lead to normalized effective conductivities that are maximum (${\sigma }_{eff}=1$), random distribution averaged (2/3), and zero conductivity. (b) Degenerate alignments yield maximum (${\sigma }_{eff}=1$) and weighted average (${\sigma }_{eff}=1/2$) conductivities.
