论文摘要
大气泡在物理实验室中主要用于研究2D湍流，表面摇摆，肥皂系统的基本特性...从更具艺术性的角度来看，吹大气泡是许多艺术表演的一部分。两个社区通常都会获得合理的泡沫电影。本文的目的是提出主要的物理成分，允许识别制作稳定膜和气泡的良好食谱。我们提出了受控的实验，以测量产生气泡及其稳定性的稳定性，以实现不同的稳定解决方案，我们通过一一添加一个成分来选择艺术家食谱中包含的成分。主要结果是（i）表面活性剂浓度必须不高（ii）溶液必须包含一些较长的柔性聚合物链，以使气泡产生易于产生，并且（iii）添加甘油可以通过避免蒸发来获得更好的气泡稳定性。我们最终提出了一个有效的食谱，该配方考虑了所有这些考虑。
Big bubbles are largely used in physics laboratories to study 2D turbulence, surface wavers, fundamental properties of soap systems... On a more artistic point of view, blowing big bubbles is part of many artistic shows. Both communities usually wan to get reasonably stable foam films. The purpose of this article is to propose the main physical ingredients allowing to identify a good recipe for making stable films and bubbles. We propose controlled experiments, to measure both the easiness to generate a bubble and its stability for different stabilizing solutions, which we choose by adding one by one the ingredients contained in an artist's recipe. The main results are that (i) the surfactant concentration must be not too high (ii) the solution must contain some long flexible polymer chains to allow an easy bubble generation and (iii) the addition of glycerol allows a better bubble stability by avoiding evaporation. We finally propose an efficient recipe, which takes into account all these considerations.
