Abstract
A model, entitled the multi-effect-coupling p H -electric-stimuli (MECpHe) model, is presented and analyzed for the response of smart hydrogels to changes in the coupled stimuli of an external electric field and the solution p H . It considers finite deformations, the electric potential and distribution of fixed charge density in the hydrogel and surrounding solvent. The MECpHe model is validated with previously published experimental measurements and good agreement is shown. A steady-state study is carried out for various p H values and applied electric voltages to ascertain the impact of these on the deformation of the hydrogel and distribution of ionic species, electric potential, and fixed charge density, both inside the hydrogel as well as in the surrounding solvent.Keywords
