Abstract :

Colloidal spheres have drawn tremendous interests in the past decades because they and their assemblies have the enhanced even novel properties and can find potential applications in coatings, catalysts, opto-electronic devices, surface-enhanced Raman scattering devices, solar cells, high-performance display units. Many physical and chemical methods have been developed to fabricate these colloidal spheres and their ordered superstructures. Recently, we have developed several novel methods, including â�?�?Pickering emulsification polymerizationâ�?, â�?�?Nano-solid- -fluid assemblyâ�?, â�?�?Oil-water interfacial self-assemblyâ�?, etc., to fabricate these spheres and their assembles. For example, oil-water interfacial self-assembly has come to be considered an ideal strategy for the assembly of various low-dimensional nanostructures into nanofilms. The low-dimensional nanostructures are well dispersed in water, and then an oil phase is added to form an oil-water interface. After the addition of an appropriate amount of inducer, the decreased interfacial energy causes the nanostructures self-assembled into closely packed monolayer nanofilms at the interface. Very recently, we have developed this self-assembly procedure to fabricate hierarchical hybrid colloidal spheres and their assemblies, and further investigated their properties and potential applications in coatings, and other fields.
