Protonation-induced molecular permeation at oil/water interface in electric field

Abstract

As a common physicochemical phenomenon, protonation can bring molecules, atoms or ions with lone-pair electrons electrified, and further cause some changes in physical and chemical properties. Our study first focused on molecular protonation progress and accompanying transitions on oil/water interfacial property in the electric field. The relationship between the protonation degree increment and applied voltage was proposed to guide for controlling the protonation via applying electric field. Besides protonation degree, water solubility of oily target molecule obviously increased at 30 V for 600 s along with electric field-driven protonation. At the same time, electric conductivity and underwater interface wettability of oil phase transited. These property transitions are anticipated to guide the further improving and updating of promising protonation functions.
