Few-layer molybdenum disulfide (MoS2) nanosheets dispersed in low-boiling ethanol solvent are prepared via the polyvinylpyrrolidone (PVP) enhanced exfoliation. The obtained MoS2-PVP nanocomposites sandwiched between reduced graphene oxide film and Al electrode exhibite the electrically bistable behavior with the function of nonvolatile rewritable memory. This study paves a way of employing two-dimensional nanomaterials as both functional materials and conducting electrodes for the future flexible data storage.
