摘要：
The emerging field of free-standing and flexible paperlike materials based on graphene sheets has become the focus of considerable research in recent years because of the scientific and technological significance of these materials. In particular, multifunctional flexible graphene-based films or papers are in high demand for various applications. Herein, we report the fabrication of magnetic, electrically conducting, and flexible paper composed of graphene and nanoscale Fe3O4 particles made using a simple simple yet versatile solution-processed approach. The conductive, magnetic, and mechanical properties of these free-standing hybrid papers with different loadings of nanoscale Fe3O4 particles were investigated. In addition to he excellent electrical conductivity and mechanical strength, the obtained flexible graphene/Fe3O4 hybrid papers also show superparamagnetism, which can be tuned easily through modulation or the loading of Fe3O4 nanoparticles. Combining all of these outstanding properties, we have fabricated and demonstrated a magnetic-controlled conductive switch using these flexible and multifunctional graphene/Fe3O4 hybrid papers.
