Thermodynamic Analysis of Nanobubbles on Hydrophobic Surface

  • 2 Accesses

The paper presents a thermodynamic analysis of the formation of an equilibrium nanobubble at a smooth, hydrophobic solid/water interface. The analysis utilizes the Kelvin equation and the electrostatic energy of the bubble/water electric double layer. The presence of the minimum Gibbs energy indicates to a possibility of self-induced generation of nanobubbles, their equilibrium and long-term stability.
