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 contrib…

Transient sliding of thin hydrogel films: the role of poroelasticity
Lola Ciapa, Jessica Delavoipi\ère, Yvette Tran +2
We report on the transient frictional response of contacts between a rigid spherical glass probe and a micrometer-thick poly(dimethylacrylamide) hydrogel film grafted onto a glass…
