| 中文摘要 | the aggregation of rod-flexible aba and bab triblock (a was rod block and repulsive with block b) copolymers in a thin film was studied as a function of varying the rigidity (eta) and the length of the rod block by monte carlo simulation. the rigidity of block a was defined as eta = r-c/r-max in this study. r-c, was the end-to-end distance below which the conformation of the block was not allowed, whereas r-max, was the longest end-to-end distance that the block could be. if eta = 0 the block was flexible, whereas if eta = 1 the block was a straight rod. the simulation results showed that the aba triblock copolymer film were likely to form lamella structure with increasing the rigidity (eta) of block a. the lamellas were parallel each other and perpendicular to the film surface. however, the aggregation of bab triblock copolymers tended to change from lamella to cylinder structure with increasing the rigidity (eta) of block a. typical lamella and cylinder co-exist structure was obtained at eta = 0.504 for the bab copolymer film. on the other hand, the simulation results indicated that the film changed from disorder to order, then to disorder structure with increasing the relative length of b block for both aba and bab copolymer films. |
