研究了对称的两嵌段共聚苯乙烯(S)和甲基丙烯酸甲酯(MMA)薄膜的形态与薄膜厚度的关系，其中总厚度小于或等于3L/2，其中L为整体片层微区的周期。在所有情况下，都发现了平行于薄膜表面的层状、片层的形态，但发现PS和PMMA层的厚度以及层与层之间的界面宽度随着薄膜厚度的变化而变化。
The morphology of thin films of symmetric, diblock copolymers of styrene (S) and methyl methacrylate (MMa) was studied as a function of film thickness where the total thickness of the films was less than or equal to 3L/2 where L is the period of the lamellar microdomain in the bulk. In all cases, a layered, lamellar morphology oriented parallel to the surface of the film was found but the thicknesses of the PS and PMMA layers and the width of the interface between the layers were found to vary with film thickness.
