Fluid-fluid interfaces are attractive for reacting dislike materials and thus for the preparation of hybrid, higher order structures. The Pentzer lab has developed 2D carbon-based nanosheets as particle surfactants and shown that by simple chemical modification, they can be assembled at different fluid-fluid interfaces: oil-water, oil-oil, ionic liquid-water, ionic liquid-oil, gas-water, etc. Further, we have demonstrated the use of these Pickering emulsions to prepare a variety of composite structures based on the location of the reagents (continuous phase only, discontinuous phase only, or both). This presentation will describe the use of graphene oxide (GO) and its functionalized analogues as surfactants, and the use of simple chemical reactions to make hollow capsules, filled capsules, armored polymer particles, and Janus nanosheets. The diversity of applications these diverse structures will also be briefly described, highlighting the power of simple chemical reactions coupled with controlled interfacial area.<br/>
