Abstract
En 中文
Liquid–liquid encapsulation enables rapid wrapping of liquid core droplets using liquid interfacial layer(s) floating on a host liquid bath, but is conventionally limited to shell-forming liquids lighter than the host bath and suffers from uncontrolled lateral spreading of the interfacial layer. We hypothesize that introducing a simple hydrophobic loop at the air-host liquid interface will (i) anchor denser interfacial liquids by interfacial pinning, circumventing the density constraint, and (ii) confine lateral spread, allowing thicker films to form from the same volume of the interfacial layer and improving process control.
