Self-assembled graphene oxide microcapsules with adjustable permeability and yolk-shell superstructures derived from atomized droplets.
GO microcapsules were assembled on the surface of atomized droplets prepared by a spray-drying strategy. The nanochannels in the microcapsule wall can be adjusted by water-soluble polymers and make the microcapsule exhibit sustained release. The strategy can further be employed to encapsulate metal organic frameworks to obtain MOF-GO yolk-shell superstructures.
