Droplets on highly deformable, elastic surfaces exhibit unusual wetting behaviour. The deformability of the substrate alters the contact angle with respect to Young’s law, while spreading dynamics is fundamentally different from that on rigid surfaces. Here we report recent experimental and theoretical progress, and highlight some of the salient features of the solid’s surface tension.

Recent comparisons of theoretical models of contact lines with experimental results (Podgorski et al. 2001, Winkels et al. 2011, Puthenveettil et al. 2013, Benilov & Benilov 2015) show that, in some cases, the most popular model – based on the Navier-slip condition and a prescribed contact angle – works only if the slip length is unreasonably small (subatomic).
