Query: Statics of polymer droplets on deformable surfaces   The equilibrium properties of polymer droplets on a soft deformable surface
are investigated by molecular dynamics simulations of a bead-spring model. The
surface consists of a polymer brush with irreversibly end-tethered linear
homopolymer chains onto a flat solid substrate. We tune the softness of the
surface by varying the grafting density. Droplets are comprised of bead-spring
polymers of various chain lengths. First, both systems, brush and polymer
liquid, are studied independently in order to determine their static and
dynamic properties. In particular, using a numerical implementation of an AFM
experiment, we measure the shear modulus of the brush surface and compare the
results to theoretical predictions. Then, we study the wetting behavior of
polymer droplets with different contact angles and on substrates that differ in
softness. Density profiles reveal, under certain conditions, the formation of a
wetting ridge beneath the three-phase contact line. Cap-shaped droplets and
cylindrical droplets are also compared to estimate the effect of the line
tension with respect to the droplet size. Finally, the results of the
simulations are compared to a phenomenological free-energy calculation that
accounts for the surface tensions and the compliance of the soft substrate.
Depending on the surface/drop compatibility, surface softness and drop size, a
transition between two regimes is observed: from one where the drop surface
energy balances the adhesion with the surface, which is the classical
Young-Dupr\'e wetting regime, to another one where a coupling occurs between
adhesion, droplet and surface elastic energies.
