蒙特卡罗模拟被用来在 A/B/( 块共聚物) 与不同体系结构调查多块共聚物的 compatibilizing 行为第三的混合。homopolymer A 的体积部分,作为驱散的阶段采用了,是 19% 。模拟说明 di 块或多块共聚物怎么在接口聚集并且影响如此的不兼容的聚合物混合的阶段行为。而多块链在接口上躺着, di 块共聚物链在接口上趋于到“看台”。与 di 块共聚物比较,有 4,或 10 块的块共聚物能在接口上占据更多的区域,并且因此,多块共聚物为阶段分离的延迟有更高的效率。
The surface-induced effect on the morphologies of lamella-forming diblock copolymers in nanorod arrays is studied by using the self-consistent field theory. In the simulation study, a rich variety of novel morphologies are observed by variations in the strength of the surface field for the diblock copolymers. Different surface-field-induced effects are examined for the diblock copolymers in the arrays with distinct preferential surfaces. It is observed that the majority-block preferential surfaces have more obvious induced effects than those of minority-block preferential surfaces. The strong surface fields exhibit different behaviours from those observed in the weak surface fields, by which the morphologies possess cylindrical symmetries. Results from this research deepen the knowledge of surface-induced effects in a confinement system, which may aid the fabrication of polymer-based na^omaterials.
