中文摘要：
采用耗散粒子动力学（Dissipative Particle Dynamics，DPD）方法模拟两平行平板间的双嵌段共聚物体系的介观结构．模拟结果表明，随板间距的增大，体系分层数量的增加是不连续的，在分层数量的增加过程中，出现不规则结构的过渡区；聚合物链末端距随板间距的增大呈周期性振荡，振荡幅度逐渐减小．对模拟结果的分析表明：层状结构转变点与分层数量之间存在近似线性关系；层状结构转变点近似与共聚物链长的2／3次方成正比．
英文摘要：
Simulation of the meso-scale structures of diblock copolymers between two parallel plates is performed using dissipative particle dynamics （DPD）. The simulation results show that the＇discontinuous increase of number of layers appears in meso-scale sandwich structure with an existence of atactic transition, when the plate-to-plate distance increases. An approximately linear relationship exists between the sandwich structure conversion, which is approximately in proportion to the 2/3th power of the chain length of copolymer, and number of layers. The end-to-end distance of copolymer chain presents a periodic oscillation behavior, and the amplitude decreases gradually, when the plate-to-plate distance increases.
