摘要: The dewetting behavior of a liquid film from substrate has been studied as function the viscosity, using two highly viscous polymers model system. velocity exhibits minimum viscosity. This results competition (1) mass transport in substrate, and (2) retarded deformation liquid-liquid interface. Atomic force microscopy is used to image both liquid-air interfaces buried shape latter changes significantly with increasing
