Measurement of Dynamic Surface Tension by Mechanically Vibrated Sessile Droplets Reviewed International coauthorship International journal

Review of Scientific Instrumments 87 ( 4 ) 045106 2016.04

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal) Publisher：American Institute of Physics

We developed a novel method for measuring the dynamic surface tension of liquids using mechanically vibrated sessile droplets. Under continuous mechanical vibration, the shape of the deformed droplet was fitted by numerical analysis, taking into account the force balance at the drop surface and the momentum equation. The surface tension was determined by optimizing four parameters: the surface tension, the droplet’s height, the radius of the droplet-substrate contact area, and the horizontal symmetrical position of the droplet. The accuracy and repeatability of the proposed method were confirmed using drops of distilled water as well as viscous aqueous glycerol solutions. The vibration frequency had no influence on surface tension in the case of pure liquids. However, for water-soluble surfactant solutions, the dynamic surface tension gradually increased with vibration frequency, which was particularly notable for low surfactant concentrations slightly below the critical micelle concentration. This frequency dependence resulted from the competition of two mechanisms at the drop surface: local surface deformation and surfactant transport towards the newly generated surface.

This paper reports the use of a micro X-ray CT scan system to measure the viscosity increase during in-situ gelation of a gelcasting slurry. Three small steel balls were dropped in the slurry at a desired time interval after the addition of the gelling agent, while being monitored by the CT scan system. It was determined that the plot of the logarithm of the calculated viscosities based on the settling velocity of the falling ball versus the gelation time can be classified into three regions with increasing slopes. The first region is designated as the idle time during which the gelcasting slurry can be further processed and cast into a mold. These condregion is the on set of gelation during which the polymer networks start to form with a gradual increase in the viscosity, whereas the third region is attributed to the increased concentration of the polymerized networks as typified by the significant increase in the slurry viscosity. Moreover, the falling ball method was found to be more sensitive to detecting the onset of gelformation in the gelcasting slurry than stress-controlled rheometric analyses.
