NOVELTY - Preparing graphene/polymer complex material, comprises dispersing reduced graphene or high quality graphene in the polar solvent, ultrasonically adding polymer and mixing uniformly, and drying to obtain complex material. USE - The method is useful for preparing graphene/polymer complex material (claimed). ADVANTAGE - The method has simple preparation process, and is easy to operate and economical. The complex material has improved strength and low-temperature toughness; is harmless to the environment; and is suitable for large scale application.
