| Summary: | Title screen Solid surfaces with chemical patterning or topographical structure have attracted attention due to many potentialapplications such as manufacture of flexible electronics, microfluidic devices, microscale cooling systems, aswell as development of self-cleaning, antifogging, and antimicrobial surfaces. In many configurations involvingpatterned or structured surfaces, liquid films are in contact with such solid surfaces and the issue of film stabilitybecomes important. Studies of stability in this context have been largely focused on specific applications andoften not connected to each other. The purpose of the present review is to provide a unified view of the topicof stability and rupture of liquid films on patterned and structured surfaces, with particular focus on commonmathematical methods, such as lubrication approximation for the liquid flow, bifurcation analysis, and Floquettheory, which can be used for a wide variety of problems. The physical mechanisms of the instability discussedinclude disjoining pressure, thermocapillarity, and classical hydrodynamic instability of gravity-driven flows.Motion of a contact line formed after the film rupture is also discussed, with emphasis on how the receding contactangle is expected to depend on the small-scale properties of the substrate.
