Abstract:
The surface active properties of the vapor of volatile, inert fluorocarbon compounds such as C6F14, C8F18, and C10F18 have been discovered. In a newly observed phenomenon of capillary instability, permanent oscillatory and rotary motions occur in many fluids, due to a 10–30% reduction in the surface tension of a fluid when in contact with fluorocarbon vapors at room temperature. The features and possible uses of the effect and prospects for finding new types of volatile surfactants are discussed.
