Contact angle and stability of interfacial nanobubble supported by gas monolayer.

ABSTRACT: Since solid-liquid interfacial nanobubbles (INBs) were first imaged, their long-term stability and large contact angle have been perplexing scientists. This study aimed to investigate the influence of internal gas density and external gas monolayers on the contact angle and stability of INB using molecular dynamics simulations. First, the contact angle of a water droplet was simulated at different nitrogen densities. The results showed that the contact angle increased sharply with an increase in nitrogen density, which was mainly caused by the decrease in solid-gas interfacial tension. However, when the nitrogen density reached 2.57 nm^-3, an intervening gas monolayer (GML) was formed between the solid and water. After the formation of GML, the contact angle slightly increased wi
