用真实的二维自洽场理论（SCFT）研究了两亲性嵌段共聚物AB/均聚物C二元共混物在稀溶液中囊泡的形成.特别注意的是发挥了作用的均聚物C在控制囊泡的形成。在模拟中，人们发现，随着均聚物C的平均体积分数的减少，而保持总的平均体积分数的嵌段共聚物AB和均聚物C不变，有一个形态从双层囊泡的棒状/环状胶束的过渡。在模拟中观察到复合囊泡结构。当嵌段共聚物AB的平均体积分数进一步增加而AB和C的总平均体积分数保持不变时，复合囊泡结构变得比单层囊泡结构更不利于熵。考察了均聚物C的聚合度对两亲体系囊泡形成的影响。通过将均聚物C的聚合度降低至1，组分C变成与本体溶剂不混溶的小溶剂分子。结果发现，小溶剂C对囊泡的形态稳定性没有影响。
The formation of vesicles in a binary blend of an amphiphilic diblock copolymer AB/homopolymer C was studied in a dilute solution using the real space two-dimensional self-consistent field theory (SCFT). Special attention was played to the role played by the homopolymer C in controlling the vesicle formation. In the simulations, it was found that as the averaged volume fraction of homopolymer C was decreased while keeping the total averaged volume fraction of block copolymer AB and homopolymer C unchanged, there was a morphological transition from the bilayer vesicles to rod-like/circle-like micelles. The compound vesicle structure was observed in the simulations. When the averaged volume fraction of block copolymer AB was further increased while the total averaged volume fraction of AB and C remained unchanged, the compound vesicle structure became less favored entropically than the unilamellar vesicle structure. The effect of the degree of polymerization of the homopolymer C on the vesicle formation of the amphiphilic system was examined. By reducing the degree of polymerization of the homopolymer C to unity, the component C became a small solvent molecule immiscible with the bulk solvent. It was found that the small solvent C exerted no influence on the morphological stability of the vesicles.
