Slippery liquid-infused porous surfaces and droplet transportation by surface acoustic waves [PDF]
, 2017 On a solid surface a droplet of liquid will stick due to the capillary adhesion and this causes low droplet mobility. To reduce contact line pinning, surface chemistry can be coupled to micro- and/or nano-structures to create superhydrophobic surfaces on
