Title: Computer simulation of structure and microphase separation in model A-B-A triblock copolymers

Source: Physical Review E - Statistical, Nonlinear, and Soft Matter Physics

Year : 2002

Abstract:

A set of computer simulations for three symmetric A-B-A triblock copolymer microarchitectures at varying temperatures is reported. By using the cooperative motion algorithm we obtain energy, specific heat, end-to-end distance, and bridging fraction as a function of the reduced temperature. The order-disorder transition temperatures are determined, an outline of a symmetric A-B-A triblock copolymer phase diagram is presented, and the visualization of different microstructures is given. A bicontinuous microstructure is reported at 67% fraction of A component.
