Using these values, interfacial tension
can be calculated as listed in Table 3.
The dynamic interfacial tension
between various surfactant concentrations and crude oil were measured as shown in Figure 2.
Fig 1 shows that interfacial tension
can be ultra low when the contact time is between 0~60 minutes.
47] pointed out the fact that, because of the very low interfacial tension
of this binary system, the dispersed phase actually exists as stable fibers of extremely small diameter between 50 and 200 nm.
Therefore, a high-pressure hightemperature optical cell system was assembled with other facilities to adapt reservoir condition contact angle measurements by DDDC technique and oil-water interfacial tension
measurements using the drop shape analysis technique in the current study.
The air/water interfacial tensions
of PVA solution, PVA--EPC solution, HmPVA solution, and HmPVA--EPC conjugate solution were measured on a surface tension meter (SEO, DST 60, South Korea).
Most of the papers on the subject of multiphase blends showed that the morphology of ternary blends can be predicted through the knowledge of interfacial tension
between the components of the blends (23-34).
GM]], evaluated from solid-water interfacial tension
The formation of such graft copolymer at the interface in these reactive blends acts as an emulsifier, which would decreases the interfacial tension
and suppresses coalescence between the initially immiscible polymer phases resulting in stable morphology.
Using such models to predict/fit the viscoelastic properties of the blends need or result the interfacial tension
Remaining in the work are the chapters on interfacial tension
, contact angles, colloidal dispersions, surfactants, interfacial stability, transport effects on interfacial stability, and interfacial dynamics, although they have been updated and often expanded.
c] the density of the continuous phase, [DELTA][rho] the density difference between the continuous and dispersed phase, [sigma] the interfacial tension
