A density functional theory approach to interpret elastowetting of hydrogels
Priyam Chakraborty, Surjyasish Mitra, A-Reum Kim +2
Sessile hydrogel drops on rigid surfaces exhibit wetting/contact morphology intermediate between liquid drops and glass spheres. Using density functional theory, we reveal the cont…
