Abstract

This paper describes measurements of solute and solvent transport in swollen, swelling, and collapsing hydrogels. Solute diffusion in swollen gels follows Fick's law, with diffusion coefficients varying only slightly with the degree of swelling. Solvent diffusion into swelling gels is affected both by Fick's law and by the rates of ion exchange. Solvent diffusion in collapsing gels is faster than that in swelling gels, and is effectively described by Fick's law.
