Abstract: Polymer/graphene nanocomposites can achieve some special performance like high strength, light weight, good heat resistance and electrical conduction. The paper reviewed the most recent industrialized situation of graphene at home and abroad as well as the status in the self-healing research of graphene. Moreover, state of the art for polymer/graphene nanocomposites were discussed, which included unique self-repairing performance, drug controlled release, metal anti-corrosion, electrical conduction, photocatalysis, microwave absorption and energy storage. The future application prospect of polymer/graphene nanocomposites was discussed especially in the fields of biomedical, electronic and new energy.
