We own a patented technology for producing GO aerogels starting from an alcoholic dispersion of graphene oxide. The procedure is developed under isothermal and isobaric conditions, and it is readily reproducible, scalable and cost-effective, leading to a non-reduced end-product.
The aerogel obtained combines stability and robustness with a high functionalization capacity granted by the large number of functional groups maintained from the starting graphene oxide. Aerogels obtained have a high surface area, ca. 250 m2/g, and a high pore volume, between 0.9 and 1.5 mL/g.
The possibility of preparing multifunctional composites using graphene oxide as a basic unit for the controlled self-assembly of 3D carbon macrostructures by supercritical CO2 is enormous. Possible applications include adsorption material in membrane technologies, batteries, supercapacitors, metal catalyst supports, among others.
