A theoretical description of the lamellar-in-lamellar self-assembly of binary A-b-(B-b-A)(m)-b-B-b-A multiblock copolymers in the strong segregation limit is presented. The essential difference between this binary multiblock system and the previously considered C-b-(B-b-A)(m)-b-B-b-C ternary multiblock copolymer system is discussed. Considering the situation with long end blocks, the free energy of the lamellar-in-lamellar self-assembled state is analyzed as a function of the number k of "thin" internal lamellar domains for different numbers m of repeating (B-b-A) units and different values of the Flory-Huggins chi(AB) interaction parameter. The theoretical predictions are in excellent agreement with the available experimental data.
本文给出了二元A-b-(B-b-A)(m)-b-B-b-A多嵌段共聚物在强分离极限下片层-片层自组装的理论描述。讨论了该二元多嵌段体系与先前考虑的C-b-(B-b-A)(m)-b-B-b-C三元多嵌段共聚物体系之间的本质区别。考虑到长端嵌段的情况，分析了片层-片层自组装态的自由能随“薄”内部片层域数量k的变化关系，其中k是针对不同数量m的重复(B-b-A)单元以及不同的弗洛里-哈金斯χ(AB)相互作用参数值。理论预测与现有的实验数据高度吻合。
