- Abstract:
-
A foam film made of pure liquid can be stabilized by evaporation. This is demonstrated experimentally for water and alkane films formed in a Scheludko cell at controlled saturation of the ambient air. A mechanism of the stabilization is proposed: evaporation leads to a local decrease of the temperature in the centre of the film; the meniscus acts as a thermostat and maintains a higher temperature at the film periphery. The resulting temperature gradient brings about a surface tension gradient...
