Uniform emulsion by membrane emulsification

Uniform emulsions of fluorinated liquid droplets in water are formed from SPG (Shirasu porous glass) membrane emulsification. The fluorinated oil-in-water emulsions exhibit unusually stability, as the much denser fluorinated liquid droplets do not coalesce at least 3 month after emulsification. A su...

Zusammenfassung:	Uniform emulsions of fluorinated liquid droplets in water are formed from SPG (Shirasu porous glass) membrane emulsification. The fluorinated oil-in-water emulsions exhibit unusually stability, as the much denser fluorinated liquid droplets do not coalesce at least 3 month after emulsification. A subsequent polymerization of monomer mixtures of the fluorinated droplets yields uniform polymeric microspheres encapsulating the fluorinated fluid. The use of expanded PTFE membrane emulsification forms water-in-oil emulsions with uniform liquid droplets, especially when small amount of fluorinated liquid is present in the oil phase.
