Elastic instability of polymer-shelled bubbles formed from air-in-oil-in-water compound bubbles

摘要

We study the stability of polymer-shelled bubbles with controlled dimensions generated from air-in-oil-in-water (A/O/W) compound bubbles. We show that the ratio of the shell thickness to bubble radius is critical in generating un-deformed polymer-shelled bubbles from A/O/W compound bubbles. In addition, the effects of shell stiffness and encapsulated gas on bubble stability are also investigated.
