Simulation Study on Dissipative Particle Dynamics of The Self-assembly of Di-block Copolymer in Body

Dissipative particle dynamics( DPD) method was used to study the self- assembly of diblock copolymer in body. Ratios between diblock copolymers,interaction parameters between two blocks,and box sizes are varied to study the influence on the self- assembled structures.These simulation results are consistent with the theoretical prediction and experimental results.We find that dissipative particle dynamics simulation method is an important and suitable method to study the self- assembly of block copolymers.
