Ultra-Robust Graphene Oxide-Silk Fibroin Nanocomposite Membranes



original image

Ultra-robust graphene oxide-polymer nanocomposite membranes are presented. The membranes are fabricated by the spin assisted layer-by-layer (SA-LbL) technique and exhibit ultrahigh elastic moduli and outstanding mechanical properties due to complex interactions between the components. A model of the reinforced interphase region is proposed to account for the extraordinary mechanical reinforcement, which fits the experimental data excellently.
