First, the structural characteristics and self-assembly mechanism of Rod-coil block copolymers are introduced, and then a dissipative particle dynamics model is constructed to simulate the self-assembly process. The simulation results show that with the increase of system temperature, the Rod-coil block copolymers will self-assemble into different structures, such as filamentous, membranous and composite structures. Further analysis reveals that the formation of these structures is closely related to factors such as the length, relative content, molecular weight and temperature of the Rod-coil block copolymers. The results of this study provide an important theoretical basis for a deeper understanding of the self-assembly mechanism of Rod-coil block copolymers.【Keywords】Rod-coil block copolymers; self-assembly; dissipative particle dynamics simulation; structure
