Description
Summary:Janus cages with a bilayer polymer–inorganic composite shell are synthesized by an emulsion interfacial self-organized sol–gel process followed by a polymer grafting onto the interior surface containing a vinyl group. Binary surfactants experience a phase separation to create transverse channels across the shell. The Janus cages can be functionalized by either growing responsive polymers or integrating with functional nanoparticles. They are promising in controlled loading and triggered release of desired materials under guidance.
