Tuneable cellular-structured 3D graphene aerogel and its effect on electromagnetic interference shielding performance and mechanical properties of epoxy composites

Controllable 3D graphene aerogel–epoxy composites (GA–EP) were fabricated. The pore size and morphology of GA were tuned using varied graphene oxide (GO) size and the macroproperties of GA–EP can be tailored by changing the size of GO sheets.
