Kinetics of smart hydrogels responding to electric field: A transient deformation analysis
چکیده انگلیسی

A multiphysics model is presented in this paper for simulation of kinetics of the smart hydrogels subject to an externally applied electric field, especially for analysis of the transient deformation of the hydrogel. The model termed the multi-effect-coupling electric stimulus (MECe) takes account of the coupled chemo-electro-mechanical multiphysics domains and the multi-phase effect of polymeric network and interstitial liquid as well as ionic species. The MECe model is validated well by transient simulation and comparison with available experimental data. Kinetics of ionic concentration of diffusive species is simulated. Parameter studies on the hydrogel displacement are conducted in detail for influences of externally applied electric voltage, initially fixed-charge density and surrounding bath solution concentration.
