▎ 摘　　要

Graphene-based sponge is a novel hemostatic material prepared by chemical cross-link of graphene oxide. It has a fast fluid absorption capacity to quickly absorb blood from wounds, activate clotting pathways, and achieve rapid hemostasis. In addition, graphene-based sponge is also a good platform carrier. It can be prepared by organic cross-linking, compounding with inorganic clay, and adding bioactive factors to enhance coagulation stimulation. By these methods, the hemostatic performance of the sponge is further improved, which shows great potential for application in the field of trauma hemostasis. This article reviews the research progress of graphene-based sponges from three different preparation strategies (organic cross-linking, inorganic compounding and adding bioactive factor), summarizes their hemostatic mechanisms, and prospects the development of graphene-based hemostatic sponges.
