Sažetak

An apparatus is described for simultaneous measurement of the surface tension and surface potential of films at the liquid/air interface in dynamic, steady states. Films are spread in a Langmuir type trough and perturbed by linear cyclic sweeping at predetermined rate s and compression ratios in a wide range. Information is obtained on elasticity, electrification, direction and extent of energy transfer, and on the relaxation behavior.
