Dispersion Medium

 

a continuous phase (body) in whose volume another (dispersed) phase is distributed in the form of small solid particles, droplets of liquid, or bubbles of gas. A dispersion medium may be solid, liquid, or gaseous; it forms disperse systems in combination with the dispersed phase.

For the contrast-variation measurements, the mass density of aqueous dispersion medium was raised by adding sodium chloride or sucrose to the latex dispersions.
Figure 3 displays integrated SAXS intensity distribution of the latex dispersion taken with the salt content in the dispersion medium ranging between 0 and 17 wt%.
The explanation that w/o emulsions are stable because an electric double layer exists at the interface seems untenable since the dielectric constant of the dispersion medium is low.
Emulsion type is established easily by determining the properties of its dispersion medium: the ability of an emulsion to wet a hydrophobic surface; its potential to be diluted with water; the ability of an emulsion to be colored when dye, which dissolves in the dispersion medium, is introduced and the electric conductivity of an emulsion.
It should be noted that higher latex yields were obtained with the more polar dispersion medium for a constant initiator concentration.
The dispersion medium components were 2-methoxyethanol (Sigma Chemical Co.
0] is the viscosity of the pure dispersion medium and [eta] is the intrinsic viscosity (2.
w] in the latter is that the stabilizing layer for the polymerically stabilized latex does not extend as far into the dispersion medium, enabling more particles to be packed into the same volume of water while maintaining a relatively low viscosity.
