Three-dimensional simulation of hexagonal phase of a specific polymer system under shear : The dynamic density functional approach
The first three-dimensional (3D) simulation of meso-phase formation in a specific polymer system-55% aqueous solution of the triblock polymer surfactant (EO)(13)(PO)(30)(EO)(13)-under simple steady shear is performed. The method is based on dynamic mean-field density functional theory. The hexagonal phase is investigated. The simulations reproduce recent experimental observations on the same polymer system.
