理论预测，从固体表面的均匀液体膜的去湿可以通过液体上的不稳定表面波进行。这种现象，通常被称为亚稳去湿，在许多系统中一直在寻求。在液晶和液态金属膜中的观察表明，正如预期的那样，新兴的结构与混合物中的亚稳分解所发现的结构相似。然而，某些差异，可以归因于在这两个不同的系统中的润湿力的特性，从而展示了润湿力中固有的非线性的作用。
Theory predicts that dewetting of a homogeneous liquid film from a solid surface may proceed via unstable surface waves on the Liquid. This phenomenon, usually termed spinodal dewetting, has been sought after in many systems. Observations in liquid crystal and Liquid metal films showed that, as expected, the emerging structures were similar to those found for spinodal decomposition in mixtures. Certain differences, however, could be attributed to peculiarities of the wetting forces in these two dissimilar systems, thereby demonstrating the role of nonlinearities inherent in the wetting forces.
