| Abstract |
A polymer gel is considered as a mixture consisting of a highly elastic elastic material and a liquid (solvent) dissolved in it. Based on the generalized Mooney-Rivlin model, an expression for free
energy is proposed that describes the deformation behavior and thermodynamic properties of polymer
gels. In this model, it is assumed that the Mooney-Rivlin “constants” depend on the concentration of
the liquid dissolved in the polymer. From this expression, the constitutive relations for the stress tensor, the chemical potential of the solvent, and the osmotic stress tensor are obtained. Based on these
relations, an experimental study of the deformation properties of cross-linked elastomers of various
chemical natures swollen in a solvent is performed. In particular, the dependence of the elastic properties of elastomers on the concentration of the solvent is studied and the parameters describing this
dependence are determined. |
