متن کاملUse of the Pendant Drop Method to Measure Interfacial Tension
In this paper the pendant drop method to measure interfacial tension between molten polymers is reviewed. A typical pendant drop apparatus is presented. The algorithms used to infer interfacial tension from the geometrical profile of the pendant drop are described in details, in particular a new routine to evaluate correctly the value of the radius at the apex of the drop, necessary to the calc...
متن کاملDetermining the surface tension of liquids by measurements on pendant drops
Among the numerous measuring methods for surface and interfacial tension between fluids, the optical pendant drop method is particularly elegant: It requires only a very small sample volume, not much apparatus, has few limiting conditions and is, when used correctly, a very accurate method. This article is intended to place current and future users of this method in the position of being able t...
متن کاملMacroscopic modeling of the surface tension of polymer-surfactant systems.
Polymer-surfactant mixtures are increasingly being used in a wide range of applications. Weakly interacting systems, such as SDS/PEO and SDS/PVP, comprise ionic surfactants and neutral polymers, while strongly interacting systems, such as SDS/POLYDMDAAC and C12TAB/NaPSS, comprise ionic surfactants and oppositely charged ionic polymers. The complex nature of interactions in the mixtures leads to...
متن کاملNoncontact surface tension measurement by drop rotation
Validity of the surface tension measurement technique that was proposed by Elleman et al. was experimentally verified. The technique was based on Brown and Scriven’s work on the shape evolution of rotating drops. Molten tin and aluminum drops were levitated in high vacuum by the electrostatic levitator and rotated by applying a rotating magnetic field. This technique offers an alternative techn...
