Summary

The wetting behavior of a liquid fluorocarbon on a liquid hydrocarbon was examined. At temperatures just above the freezing point of a liquid hydrocarbon there is an effect that occurs called surface freezing, where the surface of the hydrocarbon forms a periodic structure. The researchers discovered that when the hydrocarbon is coated even by the thinnest of fluorocarbon films, this surface freezing effect dissappears. Furthermore, the team researched the wetting effect of this system and discovered that, as expected, complete wetting occurred according to the <math> d </math>~,<math>\Delta T^{1/3} </math> law.
