The aim is to investigate the flexoelectric effect in 2D nanofluidic channels involving GO membranes.
Studied flexion and bending of GO membranes in humid environments
Analyzed strain gradient-induced phenomena
Measured resultant ionic potential generation
Flexing GO membranes induces ionic potentials
Ionic potentials arise from dynamic ionic streaming
Strain gradients significantly affect ion flow
Abstract
We report a flexo-ionic effect in which bending or flexing GO membranes generates ionic potentials, arising from strain gradient-induced dynamic ionic streaming potentials in humid 2D nanofluidic channels.
