中文摘要	the effects of hydrodynamic interactions on the lamellar ordering process for two-dimensional quenched block copolymers in the presence of extended defects and the topological defect evolutions in lamellar ordering process are numerically investigated by means of a model based on lattice boltzmann method and self-consistent field theory. by observing the evolution of the average size of domains, it is found that the domain growth is faster with stronger hydrodynamic effects. the morphological patterns formed also appear different. to study the defect evolution, a defect density is defined and is used to explore the defect evolutions in lamellar ordering process. our simulation results show that the hydrodynamics effects can reduce the density of defects. with our model, the relations between the flory-huggins interaction parameter chi, the length of the polymer chains n, and the defect evolutions are studied.
