We demonstrate a novel principle of contactless actuation for ionic membranes in salt
solution based on solvation. Actuation is driven by differential swelling of the sides of the …

We address the issue of the origin of the bending rigidity of a charged membrane formed
from amphiphilic molecules. Electrostatic effects are investigated by direct measurement of …

Ion‐exchange membranes, conventionally utilized in separation processes of electrolyte
solutions, are electroactive polymers that display a unique coupling between …

Understanding how ions and solvent molecules migrate within charged membranes is
fundamental for advancing the analysis of biological membranes and the design of energy …

We theoretically demonstrate the possibility of inversion of solvent migration in charged
membranes, opposing osmosis. Inversion of solvent migration is ascribed to the finite …

A variety of modeling frameworks have been proposed for ionic polymer metal composites
(IPMCs), but the physical underpinnings of their actuation remain elusive. A critical step …

The actuation strain and speed of ionic electroactive polymer (EAP) actuators are mainly
determined by the charge transport through the actuators and excess ion storage near the …

We generalize the concept of charge regulation of ionic solutions, and apply it to complex
fluids with mobile macro-ions having internal non-electrostatic degrees of freedom. The …

Functional ionomeric polymer membranes are the backbone of a wide range of ionic
devices; the mobility of ions through the ionomeric membrane is the principle of operation of …

The coupling of electric fields and charges with membrane-water interfacial fluctuations
affects membrane electroporation, ionic conductance, and voltage gating. A modified …
