Several mechanisms have been proposed in the literature defining morphological changes by the presence of nano-fillers [34]: (i) distribution of nano-fillers at the interface of polymer blends will cause interfacial tension reduction, (ii) solid barrier built by nano-fillers at the interface prevents domain coalescence, (iii) presence of solid particles increases the viscosity of the polymer domains and forms a physical network of particles immobilizing the dispersed phase, and finally (iv) coalescence inhibition by strong interaction between polymer chains and solid particles (steric hindrance).
2 wt % for both surfactants, the EMES and SDS reduce the interfacial tension with crude oil to 3.
where IFT(t) is interfacial tension as a function of time, t, IFTe is the equilibrium IFT, Co is the initial surfactant concentration, and [GAMMA] is the adsorption at the interface.
Indeed, for a low concentration of the dispersed phase, rheological behavior of the blend can be directly correlated to the size and distribution of the inclusions in the frame of Palierne's model [37], which takes into account the effect of interfacial tension and droplet size and distribution.
The procedure used for dynamic oil-water interfacial tension measurements was as follows.
As is well known, the equilibrium phase structure of a multiphase system is determined not by interfacial tension alone, but rather by the interfacial free energy which represents combination of interfacial tension and interfacial areas.
In this context, experimental measurements of interfacial tensions of PIs or PI blends were also made, and the results were correlated with surface roughness and surface topology.
There is a percolation threshold at which the coalescence is the dominant process that is affected by interfacial tension and viscoelastic behavior of the phases (28).
Liquid density was measured with a constant volume pycnometer and interfacial tension was obtained via a Fisher Autotensiomat (Du Nouy ring method).
Visual observations indicate that the HA solution mobilized the LNAPL (mineral oil) by decreasing the interfacial tension between the LNAPL and water phases.
Then we determined its interfacial tension against water with pendant drop experiments (10) at different pH levels and at different temperatures.
