Controlling the dynamics of thin liquid films (thickness ~ 10 nm to 100 nm) is an emerging strategy for micropatterning, templating applications and is equally useful for understanding natural and biological systems. Generally, thin liquid film dynamics are controlled by intermolecular forces (e.g., van der Waals forces) and capillary force. These two forces counteract each other as far as stability of thin liquid film is concerned. In the present work, model problems are discussed wherein different origins of surface tension gradient-driven flows, also known as Marangoni flows, affect the dewetting dynamics of thin liquid films resting on chemically homogeneous or heterogeneous surfaces. The chemically heterogeneous surfaces would possess wettability gradients, and therefore, a new flow contribution would arise that controls the liquid film dynamics. Three kinds of Marangoni effects are considered, namely solutal Marangoni, quadratic thermal Marangoni, and electrocapillary effects. Spatiotemporal equations governing film evolution in these problems are formulated as partial differential equations and solved through numerical techniques. Our results show that solutal Marangoni effect is generally a marginal stabilizing effect, but by suitably varying initial surfactant concentration distributions, it is possible to switch the role of wettability-based patterns, if present on an underlying substrate. Under temperature modulation, quadratic thermocapillary effect can suppress van der Waals driven instability in thin films of self-rewetting fluids (SRF). Again, in SRF thin films, the competition between wettability gradients and quadratic thermocapillary effect can profoundly modulate film profiles. Electrocapillary effect acts as a stabilizing agent by delaying film break up and dominating over the wettability gradients at initial stages of the liquid film evolution dynamics.
