Graphene Oxide(GO) and its reduced substance Graphene which underwent Hummer’s method keep their high mechanical (the highest for HOPG) strength (modulus)of HOPG, could be sufficiently functionalized on large surface area, and mass producible with low production cost. Thus it is very promising to be more applicable Graphene oxide sponge, also called as graphene oxide aerogel, gathers peoples attention because of its high surface area and its easy fictionalization, It is known as lightest material ever. It's spongy nature can be used as many other applications, but chief among them is oil spill clean-up. And the graphene aerogel itself would be able to be reused after the clean-up effort. Another application of graphene spongy is a ‘fossil’ of graphene oxide dispersion. Initial morphology of GO dispersion is maintained after freeze drying. |
