제목 One-pot fabrication of graphene oxide-patched hydrogel shell microparticles in a microcapillary device
초록 This study introduces a facile microfluidic fabrication method for generation of hydrogel shell microparticles whose interfaces were patched with graphene oxide sheets. The whole fabrication procedure was carried out in a microcapillary device. Graphene oxide sheets have an ability to adhere to both O/W and W/O interfaces. Taking advantage of this behavior, we generated monodisperse O/W/O double emulsions whose interfaces were patched with graphene oxide sheets. Selective solidification of the aqueous middle phase to the hydrogel phase gave rise to uniform graphene oxide-patched hydrogel shell microparticles. Furthermore, we demonstrated that the permeation of molecules through the shell could be controlled even to small molecular length scales due to the adsorption of graphene oxide.
