We examine the fully nonlinear behavior of a thin liquid film on a hydrophobic/hydrophilic solid support in three dimensions using a phase field model. For flat homogeneous substrates, the stability of thin liquid layers is investigated under the action of gravity. The coarsening process at the solid boundary can be controlled on inhomogeneous substrates. On substrates chemically patterned in an adequate way with hydrophobic and hydrophilic spots, one can obtain stable, regular liquid droplets and even design liquid structures (PACS numbers: 47.54.-r, 68.18.Jk, and 05.70.Np).
我们使用相场模型在三维空间中研究了疏水/亲水固体支撑物上薄液膜的完全非线性行为。对于平坦的均匀基底，研究了重力作用下薄液层的稳定性。在非均匀基底上可以控制固体边界处的粗化过程。在以适当方式化学图案化有疏水和亲水斑点的基底上，可以获得稳定、规则的液滴，甚至设计液体结构（物理和化学分类号：47.54.-r、68.18.Jk和05.70.Np）。
