Abstract

Line tension is calculated for a simple model of a surface nanobubble formed on a smooth hydrophobic substrate. It is shown that, with an increase in the contact angle at a certain critical value, the surface tension changes sign from positive to negative. This means that the surface tension stretches the nanobubble, increasing its radius of curvature and thereby stabilizing it.

为表面纳米气泡的简单模型计算线张力

摘要

针对在光滑的疏水性基底上形成的表面纳米气泡的简单模型计算线张力。结果表明，在一定的临界值下，随着接触角的增加，表面张力从正变负。这意味着表面张力拉伸了纳米气泡，增加了其曲率半径，从而使其稳定。
