采用动态平均场密度泛函方法来描述存在几何约束的相分离。我们观察到，小填充颗粒（如棒）的内含物已经对聚合物熔体的形态产生了巨大的影响。其效果与应用简单稳定剪切的效果相当。存在较大填充颗粒（如板）时的介观结构完全由颗粒的几何形状决定。详细研究了聚合物表面相互作用对形貌形成的影响。
The dynamic mean-field density functional method is adapted to describe phase separation in the presence of geometrical constraints. We observe that inclusion of small filler particles (such as rods) already has a dramatic effect on the morphology of polymer melts. The effect is comparable to the effect of applied simple steady shear. Mesostructures in the presence of large filler particles such as plates are totally governed by the geometry of the particle. Effects of polymer–surface interactions on morphology formation are investigated in detail.
