Abstract:

 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.

Key words: triblock copolymer, selfassembly, dissipative particle dynamics
