Bursting of a Liquid Film on a Liquid Substrate

This is the authors' abstract. We don't add key points for this paper.

We study metastable PolyDimethylSiloxane (PDMS) films deposited on a substrate of fluorinated PDMS: after nucleation, a hole grows at constant velocity V. V is inversely proportional to the substrate viscosity and is proportional to - S , where S (< 0) is the spreading parameter. The velocity is a decreasing function of the film thickness e ; the detailed V(e) law can be interpreted by a balance between capillary forces and viscous forces acting on an almost flat rim.
