This article highlights our recent achievement on directing nanoparticles to self-assemble at the water/oil interface. We demonstrate that contact angle of 90° is prerequisite for localize interface, which determined by terminal groups capping ligands. With this peculiar surface wettability, different sizes and chemical composition may into homogeneous or composite thin films The interfacially active be employed stabilize water-in-oil oil-in-water droplets, creating microcapsules whose shells are composed randomly close packed nanoparticles. permeability resulting defined used.
