| 中文摘要 | we have studied, both experimentally and theoretically, the aggregation morphology of the aba amphiphilic triblock copolymer in dilute solution by changing the solvent property. experimental results showed that the micellar morphology changed from spheres to rods and then to vesicles by changing the common solvent from n-n-dimethylformamide (dmf) to dioxane and then to tetrahydrofuran (thf). these controllable aggregates were also obtained by monte carlo simulation. the simulative results showed that the solvent property is a key factor that determines the copolymer aggregation morphology. the morphology changed from spheres to rods and then to vesicles by increasing the solvent solubility, corresponding to the change of stretched of the copolymer chains in the micellar cores. this result is in good agreement with the experimental one. moreover, the simulative results revealed that the end-to-end distant of the aba triblock copolymer in the vesicle was larger than that in the spheres and rods, indicating that the copolymer chains were more stretched in vesicles than in the spheres and rods. furthermore, we gave the distribution of the fraction of the chain number with the end-to-end distance. the results indicated that the amount of folded chains is almost the same as that of stretched chains in the vesicle. although most chains were folded, stretched chains could be found in the rod and sphere micelles. |
