Monte Carlo simulation of phase separation of A/B/A‐B ternary mixtures
Authors:Haojun Liang  Xuehao He  Wei Jiang  Bingzheng Jiang
Abstract:Monte Carlo simulations were used to model A/B/A‐B ternary mixtures with different AB diblock copolymer volume fractions for which both the dispersed and continuous phase volume fractions were kept constant. For concentrations of the diblock copolymer below a critical value, the domain size increment of the dispersed phase decreases linearly with the copolymer concentration. This is in agreement with the predictions of Noolandi and Hong. The dependence of the domain size as a function of the copolymer volume fraction can also be fitted by the equation of Tang and Huang. Our simulations indicate, for the first time, that the micelles form before saturation of the interface occurs. This means that the formation of the micelles is not a result of the saturation of the interface.
