Abstract:
A chemo-electro-mechanical model is presented in this paper for transient simulation of the characteristics of the kinetic ionic-strength-sensitive hydrogel. It is termed the multi-effect-coupling ionic-strength-stimulus (MECis) model and it couples the chemical and electrical as well as mechanical effects together to predict responsive characteristics of the smart hydrogel to the ionic-strength stimulus of an environmental solution based on the laws of conservation of mass and momentum. The kinetic deforming characteristics simulated by the MECis model are compared with the experiments and achieve a good agreement. Then, the influence of the initial fixed charge density, as a material property of the hydrogel, on the kinetics of the ionic-strength-sensitive hydrogel is transiently analyzed, providing a deep view of the kinetics performance of the smart hydrogel.

The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a decrease in the...
