Abstract
Here we developed a simple and novel one-step approach to produce G/O/W emulsions with high gas volume fractions in a capillary microfluidic device. The thickness of the oil layer can be controlled easily by tuning the flow rates. We successfully used the G/O/W emulsions to prepared hollow microspheres with thin polymer shells.
