Surface active properties of volatile vapors of fluorocarbon substance
s such as C6F14, C8F18, and C10F18 have been discovered. In a new phen
omenon of capillary instability some perpetual oscillatory and rotary
movements of many liquids take place due to a change of their surface
tensions by 10-30% at contact with C8F18 vapor at room temperature. Fe
atures and possible applications of volatile surfactants are discussed
.
