Self-consistent Filed Theory Study on Self-assembly of Linear ABC Triblock Copolymer in Homopolymer C

The self-assembly of linear ABC triblock copolymer in homopolymer C was studied by the real-space self-consistent field theory. The simulative results show that the dispersed phase formed by the triblock copolymer in the homopolymer is mainly the core-shell structure. Decreasing the interaction between species A and C can change the core-forming block from A to B. There are several intermediate morphologies between the two main core-shell structures, including the cylinder with bump surface, the disk with bump surface and the twist cylinders. Moreover, the structure with core-forming block B is favorable at the low content of block A in the mixture.
