Surface textures suppress viscoelastic braking on soft substrates

Martin Louis Francis Coux, John Martin Kolinski

A gravity-driven droplet will rapidly flow down an inclined substrate, resisted only by stresses inside the liquid. If the substrate is compliant, with an elastic modulus G < 100 kPa, the droplet will markedly slow as a consequence of viscoelastic braking. ...
