Oscillations of sessile drops of surfactant solutions on solid substrates with differing Hydrophobicity

von Bahr, M; Tiberg, Fredrik LU and Zhmud, B (2003) In Langmuir 19(24). p.10109-10115
Abstract
The paper reports results of experimental studies on the dynamic behavior of surfactant

olution drops on substrates with differing hydrophobicity. Contact angle

oscillations observed immediately after the drop deposition are

studied, and a mechanistic interpretation of this phenomenon is put

forward. The major emphasis is put on the physicochemical aspects of

surfactant action, including the dynamic wetting enhancement and the

effect of surface tension relaxation on the frequency of drop

oscillation, which are characteristic of surfactant

solutions. Appropriate scaling relations describing the drop dynamics

are derived.
