Asymmetric electrochemical system with tunable hydrophobicity. Complementary redox-active electrodes made of (a) PVF/PPy and (c) PPy/AOT nanostructures; scale bars are 10 μm. (b) Schematic of the asymmetric system with electrochemically modulated affinity toward uncharged organic molecules. (d) Adsorption isotherms of SOG for various applied potentials. Filled markers represent experimental data, and solid lines are fits based on the Freundlich adsorption model. Reproduced with permission from ref (104). Copyright 2019 American Chemical Society.
