用自洽场理论研究了嵌段B和C的疏水性对ABC线型三嵌段共聚物在选择性溶剂中形成聚集体形态的影响。通过改变嵌段B和C的疏水性，得到了核壳冠状、汉堡包状、节虫状等5种典型胶束。模拟结果表明，胶束的形状和大小基本上由中间嵌段B的疏水程度控制，而胶束的类型主要由末端嵌段C的疏水程度决定。
The effect of the hydrophobic properties of blocks B and C on the aggregate morphologies formed by ABC linear triblock copolymers in selective solvent was studied through the self-consistent field theory. Five typical micelles, such as core-shell-corona, hamburger-like, segmented-wormlike, were obtained by changing the hydrophobic properties of blocks B and C. The simulation results indicate that the shape and size of micelle are basically controlled by the hydrophobic degree of the middle block B, whereas the type of micelle is mainly determined by the hydrophobic degree of the end block C.
