Research Abstract

In this work, a novel technique, that allows the assembly of different types of colloid particles into ordered multicomponent clusters(suparaparticles) has been investigated. The size and the composition of the superparticle during their assembly are controlled by gathering and confining their components in a restricted, colloid size space. Emulsion droplets are used to provide their restricted apace.
The basic principle of the "assembl-and dissolution" scheme used in this study are as follows. The process starts with a suspension of latex or silica microspheres in water. Emulsion drops as the oily phase are introduced after that in the system. The particles could be adsorbed either on the droplet surface or in the their bulk. The obtained ordered shells or balls of densely packed particles are fixed together by an appropriate agent. The carrier emulsion droplets are later dissolved by adding of a mediator phase or solubilizing agent. Thus the final product is supraparticle clusters resuspended in the water phase.
One interesting possibility is the fabrication of supraparticles including more than on colloid components. We have assembled composite particles by using both the sulfate and amidine latices or silica and amidine latices by combining their assembly schemes. These composite particles consisted of a core of aggregated amidine microsphers surrounded by the shell of sulfate latices or silica particles. The process first included the formation of ball-like aggregates from the amidine latices inside the octanol droplets. We then used the method for formation of sulfate or silica latex shell on the droplet surfaces.
