We demonstrate a new strategy to tune the density of graphene aerogels. This facile method is capable of producing graphene aerogels over a wide density range without compromising the morphology or quality of the material. Perylenetetracarboxylic acid dianydride serves as a sacrificial filler material that can be thermally decomposed to yield a graphene aerogel with tunable density.
