Abstract
Abstract Highly stable microbubble dispersions with mean bubble radii of less than 100 µm stabilized solely with nonionic surfactant of glyceryl monostearate are reported, and the stability was sustained for more than 10 months which is attributed to the presence of lamellar liquid-crystal gels. The elastic response of the interface provides a physical barrier to collapse of dispersed microbubbles. Our study identifies a route to fabricate extremely stable dispersions of microbubbles.
