Abstract
. An interfacial water layer exists between the nitrogen gas and the interface, characterized by ordered hydrogen bond orientations and distinct hydrophobic properties, which collectively inhibit bubble diffusion and promote stability. Furthermore, the stable existence of nanobubbles on the mica surface was observed using quantitative nanomechanical atomic force microscopy (AFM). The stability of the nanobubbles is closely related to the structure of interfacial water, where high-density bubble structures, weak interlayer hydrogen bonding, and ordered hydrogen bond networks serve as the key factors for stable adsorption. These findings provide a theoretical foundation for understanding the microscopic mechanisms of nanobubbles at the solid-liquid interface.
