中文摘要：
利用平衡态耗散粒子动力学（DPD）方法研究了嵌段共聚物自组装形成胶束及均聚物链在其表面的吸附.采用非平衡态耗散粒子动力学（NEDPD）方法,通过加入剪切作用研究了均聚物的脱落和胶束的分裂过程.研究结果表明,在小的剪切速率下,胶束会带着均聚物滑动和滚动;在大的剪切速率下,胶束会完全破裂,组成胶束的嵌段共聚物也像均聚物一样被拉长;只有在适当的剪切速率范围内,才会有均聚物的脱落和胶束分裂的过程.通过分析给出了剪切速率大小与脱落时间的对应关系.
英文摘要：
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.
