Graphene has inspired ever-increasing enthusiasm in the past few years owing to its exceptional electrical
optical
thermal and mechanical property.Due to the intermolecular force (hydrogen bonding
π-π interactions
electrostatic) between graphene and biomass molecules
which improve the dispersion and orientation of graphene effectively and the mechanical properties of composites
thereby can broaden the application of graphene.The paper reviews the preparation methods of graphene and the application of biomass-based graphene composites.At the same time
the outlook of the application of the nanomaterials graphene is pointed out.
