我们考虑了沉积在热力学润湿的衬底上的薄膜的去湿稳定性。我们表明，如果密度波动具有足够大的振幅出现在一个膜，分离的压力在膜中的梯度destibilizes的自由表面最终导致的膜液滴破裂。这种去湿机制预计将发挥作用，在膜沉积后进行重大重组或材料接近临界点。
We consider the stability with respect to dewetting of thin films deposited on a substrate they thermodynamically wet. We show that if density fluctuations with a sufficiently large amplitude appear in a film, the resulting gradient of disjoining pressure in the film destibilizes the free surface eventually leading to the breaking up of the film in droplets. This dewetting mechanism is expected to play a role in films undergoing significant restructuring after deposition or for materials close to a critical point.
