(a) Equilibrium morphologies of AB diblock copolymers in bulk: S and S’ = body-centered-cubic spheres, C and C’ = hexagonally packed cylinders, G and G’ = bicontinuous gyroids, and L = lamellae. (b) Theoretical phase diagram of AB diblocks predicted by the self-consistent mean-field theory, depending on volume fraction (f) of the blocks and the segregation parameter, χN; CPS and CPS’ = closely packed spheres. (c) Experimental phase diagram of polystyrene-b-polyisoprene copolymers, in which f_A represents the volume fraction of polyisoprene, PL = perforated lamellae. Reproduced from Reference [69].
