“…This means that the effects due to gravity, inertia and viscosity are negligible, and the breath figures self-assembly is mainly driven by the interfacial phenomena (however, the viscosity, growing with the evaporation of the polymer solution layer, helps to stabilize the eventual honeycomb pattern, as it will be shown below). Indeed, the breath figures patterns were observed on horizontal [14][15][16] and vertical [46,[95][96][97] substrates. It is seen from Eqations 4, that the breath-figures self-assembly is a "slow" process, in which effects due to inertia and viscosity are negligible.…”
