Preparation of graphene-based aerogels by Pickering emulsion method and their performance: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 29, No 6


Pickering emulsion have been used as mushy template for the preparation of two totally different sorts of graphene-based aerogels (graphene aerogels, named AGAs and graphene/polyvinyl alcohol (PVA) aerogels, named BGAs) on this work. The Pickering emulsions present good management impact on the pore sizes, density and porosity of the 2 sorts of graphene-based aerogels. The rise of the oil/water ratio within the emulsion can results in enhance of pore measurement and porosity and reduce of density of AGAs and BGAs. And the rise of agitation velocity in the course of the emulsion preparation results in the lower of the pore sizes of AGAs and BGAs, whereas reveals slight affect on the porosity and density of the supplies. Quantity filling habits was discovered when AGAs and BGAs adsorbing organics, so it’s thought-about that prime porosity and excessive open pore fraction within the aerogels will favor the adsorption capability on organics.
