Researchers at Northwestern University have discovered that the mechanical properties of layered graphene oxide films can be significantly enhanced by mixing strong, solid graphene oxide flakes with weak, porous graphene oxide flakes. The enhancement of mechanical properties is attributed to the more compliant nature of the soft porous sheets, which act as a binder to improve interlayer packing and load transfer in the multilayer films.
