Dynamic surface tensions and dynamic surface potentials

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1993
Abstract Dynamic surface properties are investigated by means of measurements of the surface potential with time. These surface potentials were measured by the principle of the vibrating plate, using a toothed wheel which rotates around an axis parallel to that of the jet.

Measuring dynamic surface and interfacial tensions

Advanced Materials, 1992
The surface and interfacial tensions of pure liquids and surfacttant solutions can be measured using a variety of techniques including the drop volume method (see Figure) and the ring or plate method. The various methods are briefly discussed and an automated version of the drop volume method which reliably produces results of the highest quality ...

Modeling Dynamic Surface Tension on Surfactant-Enhanced Polydimethylsiloxane

Langmuir, 2021
Surfactants are often added to aqueous solutions to induce spreading on otherwise unwettable hydrophobic surfaces. Alternatively, they can be introduced directly into solid hydrophobic materials─such as the soft elastomer, polydimethylsiloxane─to induce autonomous wetting without requiring additional surface or liquid modifications.

Dynamic surface tension and surface rheology of biological liquids

Colloids and Surfaces B: Biointerfaces, 2001
The paper presents results of dynamic and equilibrium surface tension measurements (using a maximum bubble pressure instrument) of serum and urine samples that were obtained from 80 healthy human of various sexes and ages. These data were compared with surface tension measurements of biological liquids obtained from patients suffering from malignant ...

Dynamic surface tension measurements on surface active materials

Thermochimica Acta, 1986
Abstract Surface tension measurements by the Wilhelmy plate method are being done at our laboratory using an automatic balance. Surface-active material (surfactant) is spread as a monolayer on an air-water interface and a Pt plate, suspended from a micro-balance, is brought vertically into contact with the interface.

Techniques to measure dynamic surface tension

Current Opinion in Colloid & Interface Science, 1996
Recent developments of techniques used to measure dynamic surface tension aim at incorporating measurements during area changes, and improving speed of measurements, automation, and range of time scales (≤ 1 ms). New techniques incorporate better definition of surface age and of the flow field, before or during measurements. They point to truly dynamic
