Simulation Data


Small-angle x-ray scattering experiments conducted with compositionally asymmetric low molar mass poly(isoprene)-b-poly(lactide) diblock copolymers reveal an extraordinary thermal history dependence. The development of distinct periodic crystalline or aperiodic quasicrystalline states depends on how specimens are cooled from the disordered state to temperatures below the order-disorder transition temperature. Whereas direct cooling leads to the formation of documented morphologies, rapidly quenched samples that are then heated from low temperature form the hexagonal C14 and cubic C15 Laves phases commonly found in metal alloys. Self-consistent mean-field theory calculations show that these, and other associated Frank-Kasper phases, have nearly degenerate free energies, suggesting that processing history drives the material into long-lived metastable states defined by self-assembled particles with discrete populations of volumes and polyhedral shapes.


The data provided here contains the results of self-consistent field theory (SCFT) calculations. Specifically, the folder contains the input and output files for all the SCFT calculations that are shown in Fig. 1 of the main manuscript and Figs. S2-S7 of the supplemental materials. Using these files and the open source PSCF software available at, one can reproduce all the SCFT results presented in the main manuscript and its supplemental materials.
