论文摘要

如泰勒·库里克(TC)理论所描述的那样,薄膜的缩回将受到广泛的争论,特别是对于纳米级的电影。我们使用非平衡分子动力学模拟来探索连续模型中使用的假设的有效性,并通过跟踪膜中的孔的演变。通过为表面形状得出新的数学形式,并考虑缩回膜前部的局部变化表面张力,我们将原始理论与模拟数据调和,以恢复纳米级有效的校正的TC速度。

The retraction of thin films, as described by the Taylor-Culick (TC) theory, is subject to widespread debate, particularly for films at the nanoscale. We use non-equilibrium molecular dynamics simulations to explore the validity of the assumptions used in continuum models, by tracking the evolution of holes in a film. By deriving a new mathematical form for the surface shape and considering a locally varying surface tension at the front of the retracting film, we reconcile the original theory with our simulation data to recover a corrected TC speed valid at the nanoscale.
