Isosurface representation of a symmetric diblock copolymer melt for and the projection of the 3D structure factor at different dimensionless times . The surface related interaction parameter is , corresponding to the adsorption energy per statistical unit.
The part of the total free energy of a diblock copolymer as a function of time for the surface related interaction parameter .
The enlarged part of the two-cluster morphology shown in Fig. 1(e) containing the region of cluster dividing surface (the position ranges between and ). The region exhibits a doubly periodic array of saddle surfaces.
The morphology scans through the region of cluster dividing surface in the same ranges, as shown in Fig. 3. The morphologies shown are orthoslices of two-cluster morphology from Fig. 1(e) at different positions. The regions containing more blocks are colored black with linear gray scale of the density from 0.0 (black) to 1.0 (white).
Evolution of the orientational order parameter corresponding to the morphological transformations shown in Fig. 1. The surface related interaction parameter is .
The time evolution of stresses in the morphology due to domains (curve 1), (curve 2), and (curve 3).
An intermediate structure of two coexisting lamellae clusters of parallel to the electric field lamellae and the final morphology for the surface related interaction parameters (a) , (b) 0.7, and (c) 0.8. The -axis projections in the direction of the applied electric field of the morphologies are shown.
Isosurface representation of an diblock copolymer melt for and the projections of the lamellar morphology for the surface related interaction parameter , corresponding to the adsorption energy per statistical unit.
Time evolution of the orientational order parameter in the presence (solid line) and in the absence (dashed line) of an external electric field. The surface related interaction parameter is the same for both cases.
Time evolution of stresses in the subjected to the electric field sample, , due to domain transformations: (curve 1), (curve 2), and (curve 3). The transformations in stresses are related to morphological evolution shown in Fig. 8.
