Self-assembly Of Amphiphihc Abc Star Triblock Copolymer In Dilute Solution

In the paper, using self-consistent field theory(SCFT) method, we make a study on t he self-assembly of a mphiphilic A BC s tar triblock c opolymer with computer simulation. We main change chain length of A,B,C blocks and the Flory-Huggins interaction parameter with each other and then investigate the structures and the phase behavior of micelles formed in three dimensions, and then find some regulation and the process of some special structures'formation. When we analysis chain length make what affect on phase separation, we found that when we only increase chain length and the other parameters are keep unchanged, the interaction value of each other also increase, the phase separation become more and more localization and also phase separation occurred more easy. At the same time, we make compare with experiment, and found that the vesicles which with tail on the peak of its, this structures also found in experiment, but different with them, under this parameters conditions, the result calculated long enough time by computer, the structure is not the final stability structure, i s a i ntermediate transition state. A nd t he s tructure i s disappeared f inally, chang f rom vesicles to l ayers. And a t th e o ther time , novel muicellarstructures s uch a s v esicles c onnect w ith s trip w hich is d idn't found i n experiment, these structures have some predictive in experiments.
