Coupled chemo-electro-mechanical finite element simulation of hydrogels: II. Electrical stimulation

摘要: Certain polyelectrolyte gels are distinguished by a large swelling or bending capability under the influence of external physical, chemical electrical stimuli. In this paper we investigate mechanisms occurring in due to externally applied electric fields. By applying coupled chemo-electro-mechanical model which is extended and predestined for stimulation, describe concentrations potential both gel solution as well locally different shrinking gel. The local change geometry formulated osmotic pressure difference between next phase. addition effect, domain leads variation concentration bound groups thus mobile ions. As focus presented work demonstrate superiority fully description compared previously developed one-way chemo-electric mechanical model. Finally, qualitative comparison with experimental results, validity stimulation demonstrated.
