Abstract
A time-dependent Ginzburg-Landau (TDGL) model is proposed to simulate the ordering of linear triblock terpolymers. The model, in its current form, is applicable to nonfrustrated triblock systems, with the specific condition that . Simulations are presented that demonstrate the model's ability to evolve a wide variety of morphologies throughout time, including tetragonal, core-shell hexagonal, three-phase lamellar, and beads-in-lamellar phases. The model also incorporates an interaction term to study templated substrates for directed self-assembly. The efficiency of the TDGL model enables large-scale simulations that allow investigation of self-assembly, and directed self-assembly, processes that may exhibit very small defect concentrations.
