中文摘要：
利用MonteCarlo方法研究了对称ABA型双亲3嵌段共聚物刷在选择性溶液中的自组装形态．针对溶剂对A嵌段为良溶剂，对B嵌段为不良溶剂的体系，研究了亲水A嵌段长度和疏水B嵌段的长度对溶液中3嵌段共聚物刷聚集体形态的影响．模拟结果表明，随着疏水B嵌段长度的增加，共聚物自组装形态依次为球状、条状、连通条状、孔层状、层状；而随着亲水A嵌段长度的增加，共聚物的自组装形态会发生从条状相到蠕虫相的转变．
英文摘要：
The Monte Carlo method is used to study the self-assembling process of the tri- block copolymer brushes in selective solvents, which is good for the A-block but poor for the middle B-block. The influence of the block lengths, for both the soluble A-block and the insol- uble B-blocks, on the morphology of triblock copolymer brushes in solution is studied. It is shown that the morphological transitions of the aggregates, from spheres to stripes, to perfo- rated layer, and then to layer with increasing the length of the B-block, and from stripes to wormlike micelles with increasing the length of the A-block, are observed.
