Image of FIG. 1.
FIG. 1.

Schematic representation of the system considered. An triblock (,) functionalized polymer. The monomers are single beads that attract each other with characteristic energy , and with an energy to the functionalized beads.

Image of FIG. 2.
FIG. 2.

Phase Diagram as a function of monomer-monomer and monomer-functionalized end interaction for a concentration of 5% polymers at . Phases with asterisks are expected to have a narrow stability range or to be metastable.

Image of FIG. 3.
FIG. 3.

(a) Snapshot of nonfunctionalized polymers and monomers, an example of a failed template. (b) Snapshot of the perforated lamellar nanocomposite. (c) Snapshot of the perforated lamellar without the monomers showing that the perforations form a hexagonal lattice. The beads are blue and monomers purple. In all cases, the hydrophilic beads are omitted for clarity. All snapshots are created with PYMOL [Ref. 7].

Image of FIG. 4.
FIG. 4.

(a) Snapshot of a gyroid (space group ) where only beads are displayed. (b) Example of the monomers in a carpeted gyroid. (c) Monomers in a regular gyroid. In all cases, monomers are ordered with the space group.

Image of FIG. 5.
FIG. 5.

(a) Snapshot of the checkerboard lamellar phase. (b) Snapshot of the non-centrosymmetric gyroid (space group ). (c) Snapshot of the distribution of the monomers in the noncentrosymmetric gyroid (also ordered with the space group).

Image of FIG. 6.
FIG. 6.

(a) Structure factor of the gyroid (, , ) with space group with the expected location of the peaks. (b) Structure factor of the gyroid (700, 3.9, 1.8) with space group. The structure factor for monomer beads is indicated by red squares while the one for the beads is shown with blue circles.
