Linear poroelastic response of thin permeable gel films
Caroline Kopecz-Muller, Joshua D Mcgraw, Thomas Salez
When a hydrophilic and deformable porous material is immersed in a bath, it may absorb the solvent and expand by several times its volume, thus forming a highly soft and porous hyd…

Swelling and evaporation determine surface morphology of grafted hydrogel thin films
Caroline Kopecz-Muller, Clémence Gaunand, Yvette Tran +5
We experimentally study the formation of surface patterns in grafted hydrogel films of nanometer-to-micrometer thicknesses during imbibition-driven swelling followed by evaporation…

Mechanical response of a thick poroelastic gel in contactless colloidal-probe rheology
Caroline Kopecz-Muller, Vincent Bertin, Elie Raphael +2
When a rigid object approaches a soft material in a viscous fluid, hydrodynamic stresses arise in the lubricated contact region and deform the soft material. The elastic deformatio…
