The system is characterized by the total height h and the individual heights or viscosities of polystyrene (PS) and polymethylmethacrylate (PMMA) layers hPS and hPMMA or μPS and μPMMA, respectively. The PS/PMMA interface has the interfacial tension γPS-PMMA and the PS-air surface has the surface tension γPS-air. The solid-PMMA interface the slip length bs and the PMMA-PS interface the slip length bi.
