Sažetak

Liquid bridges of aqueous sodium dodecyl sulphate solutions
with different concentration between polytetrafluoro ethylene and
pyrex glass surface have been experimentally investigated. The
drop distribution isotherms are of the same type, their general
shape being independent of the surfactant concentration but the
characteristic points as the critical drop mass for total adherence
and the constant drop mass corresponding to the steady state
strongly depend on the surfactant concentration. The stability of
the bridges as well as the formation of satellite droplets after
breakdown of the bridge have been interpreted in terms of capillary
waves. A simple energetic model consideration is proposed to
explain effects caused by hysteresis.
