Molecular Control of Self-assembly Structure of Triblock Copolymers

The influence of molecular architecture of a triblock copolymer on the self-assembly morphology was investigated by dissipative particle dynamics simulation.Tuning the architecture of the triblock copolymer,we obtained different self-assembly morphologies,e.g.,ordered layered structure,small-domain disorderly-aggregated structure and distorted stage structure,etc.To reduce the system free energy as much as possible,the triblock copolymer systems with different molecular structures would spontaneously self-assemble into different ordered morphologies.
