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…

Molecular adsorption induces normal stresses at frictional interfaces of hydrogels
Lola Ciapa, Yvette Tran, Christian Frétigny +2
Friction experiments were conducted on hydrogel thin films sliding against a rigid sphere in a low velocity regime where molecular adsorption at the sliding interface sets the fric…

Friction through molecular adsorption at the sliding interface of hydrogels: Theory and experiments
Lola Ciapa, Ludovic Olanier, Yvette Tran +3
We report on the frictional properties of thin () poly(dimethylacrylamide) hydrogel films within contacts with spherical silica probes. In order to focus on the contri…
