WebOct 4, 2024 · Spherical indentation analyzed in a poroelastic framework is used to measure the permeability to fluid flow of the same hydrogels. It is found that while the diffusivity varies with exp(ξ-2), where ξ is the mesh size of the hydrogels, it also varies with exp(k-1), where k is the intrinsic permeability. For the same hydrogel structure ...
