In fluid mechanics, dewetting is one of the processes that can occur at a solid–liquid, solid–solid or liquid–liquid interface. Generally, dewetting describes the process of retraction of a fluid from a non-wettable surface it was forced to cover. The opposite process—spreading of a liquid on a substrate—is called wetting. … See more In most dewetting studies a thin polymer film is spin-cast onto a substrate. Even in the case of $${\displaystyle S<0}$$ the film does not dewet immediately if it is in a metastable state, e.g. if the temperature is below the See more Solid-state dewetting of the metal thin films describe the transformation of a thin film into an energetically favoured set of droplets or particles at temperatures well below the melting … See more WebDec 30, 2024 · The dewetting process, which is a simple and promising technique, synthesizes NPAs by breaking the as-deposited metal film into randomly distributed islands.
