由于水的高导热性和大汽化焓，通常被认为是液-气相变中性能最高的工质。然而，广泛的工业系统需要使用低表面张力的液体，其中热传递增强已被证明是沸腾和蒸发的挑战。在这里，我们启用了一种新的相变传热范例，它有利于高挥发性，低表面张力的液体而不是水。我们使用了大约600纳米厚度的纳米多孔膜
Water is often considered as the highest performance working fluid for liquid-vapor phase change due to its high thermal conductivity and large enthalpy of vaporization. However, a wide range of industrial systems require using low surface tension liquids where heat transfer enhancement has proved challenging for boiling and evaporation. Here, we enable a new paradigm of phase change heat transfer, which favors high volatility, low surface tension liquids rather than water. We utilized a nanoporous membrane of approximate to 600 nm thickness and
