Quantity of Ag_2O Created vs. Ag-plated Selemion CMV Curvature

摘要

Selemion CMV sandwiched between two silver layers (Ag-CMV) is one of IPMCs. It exhibits large bending under electrical stimulation. The bending is always accompanied by the redox reaction of silver layers. The reversible redox reaction of silver layers is induced in accordance with the induction of reversible bending. Previously, a bending mechanism for Ag-CMV was proposed. It emphasized the bending curvature of Ag-CMV is proportional to the quantity of Ag_2O created by the redox reaction of silver layers. Such a proportional relationship can be derived by assuming that the quantity of Ag_2O is proportional to the total charge applied to the Ag-CMV. XRD analysis proved that assumption, strongly supporting the validity of the bending mechanism proposed. Based on the bending mechanism, we built a model of controlling IPMC bending. It turned out to be successful prediction of IPMC bending behavior.
