Abstract The phase morphologies and phase transitions of dendrimer block copolymer thin films confined between two homogeneous, planar hard substrates had been investigated by a three-dimensional real space self-consistent field theory (SCFT). From the perspectives of property and strength of the preferential substrate, when the film system confined within neutral substrates, the thinner film was easier to take the undulated and perpendicular cylinder phases. For the attractive preference of the substrate on block segment A, the polymer films tended to take the surface-wetting structures that was composed by block segment A. On the contrary, for the repulsive preference of the substrate on block segment A, a phase transition of cylinder-lamellae could be observed increasing with the relative surface strength of the preferential substrate.

树枝状嵌段共聚物薄膜中的表面诱导相变

摘要 通过三维实空间自洽场理论（SCFT）研究了限制在两个均匀平面硬基材之间的树枝状嵌段共聚物薄膜的相形貌和相变。从优先基材的性能和强度来看，当薄膜体系局限于中性基材时，较薄的薄膜更容易呈现起伏和垂直的圆柱相。由于基材对嵌段链段 A 的吸引力偏好，聚合物薄膜倾向于采取由嵌段链段 A 组成的表面润湿结构。相反，对于基材对嵌段链段 A 的排斥偏好，相变可以观察到圆柱薄片的数量随着优先基材的相对表面强度而增加。
