Elasticity can affect droplet coalescence

Recent investigations on the coalescence of polymeric droplets a solid substrate have reported strong disagreements; heart issue is whether drops similar to that Newtonian fluid and independent molecular relaxation, or role entanglement chains leads transition kinetics different from fluid. Via this report, we resolve disagreements through discussion effects merging method dominant forces governing process, i.e., inertia, dissipation, relaxation. Our study unveils dynamics not universal in fact, it contingent by which triggered. Additionally, demonstrate spatial features bridge at time instants similarity analysis. We also theoretically obtain profile employing parameter modified thin film lubrication equation for fluids.
