摘要：

We use equilibrium dissipative particle dynamics( DPD ) method to investigate the micelle formed by self-assembly of block copolymer, where a homopolymer chain adsorbed on the surface. Under shear flow, we use non-equilibrium dissipative particle. dynamics ( NEDPD ) method to investigate the processes of the homopolymer desorption and micelle fission. The results reveal the qualitative between shear rate and desorption time.
