The effect of de-gassing on the dispersion of fine oil droplets in water

Francis, Mathew; Pashley, Richard


Several recent studies have demonstrated that a wide range of hydrophobic, water-insoluble oils can be readily dispersed in water following a simple freeze-thaw process of de-gassing. The oil droplets typically appear to be sub-micron sized and are fairly mono-disperse. They do not coalesce but slowly phase-separate or settle under gravity. This behaviour applies to a wide range of oils including, hydrocarbons, fluorocarbons and silicones. There is also some evidence that finely divided...[Show more]
