Abstract: A new mechanism of stabilizing surface nanobubbles is proposed, based on the phenomenon of contact electrification – the generation of electrical energy when water moves relative to hydrophobic surfaces. Calculations carried out on the basis of the constructed model show that the phenomenon of contact electrification can slow down the process of diffusive dissolution of surface nanobubbles and increase their lifetime.

Keywords: surface nanobubble, contact electrification, hydrophobic surface, double layer.
