Slippery and mobile hydrophobic electrokinetics: from single walls to nanochannels
arXiv:2304.14756 · doi:10.1016/j.cocis.2023.101742
Abstract
We discuss how the wettability of solid walls impacts electrokinetic properties, from large systems to a nanoscale. We show in particular how could the hydrophobic slippage, coupled to confinement effects, be exploited to induce novel electrokinetic properties, such as a salt-dependent giant amplification of zeta potential and conductivity, and a much more efficient energy conversion. However, the impact of slippage is dramatically reduced if some surface charges migrate along the hydrophobic wall under an applied field.
