Aerographene - Wikipedia
Graphene aerogels are synthetic materials that exhibit high porosity and low density. Typical synthesis of graphene aerogels involve reducing a precursor graphene oxide solution to form graphene hydrogel. The solvent can be subsequently removed from the pores by freeze-drying and replacing with air. [ 5 ] The resulting structure consists of a ...
