▎ 摘　　要

NOVELTY - Preparing the porous material based on graphene oxide and chitosan molecule assembly, comprises adding graphene oxide aqueous solution with chitosan water dispersing liquid for interface self-assembly, adding cross-linking agent to react, then adding acid treatment, freezing and drying. USE - The porous material based on graphene oxide and chitosan molecule assembly is useful in preparing hemostatic material (claimed). ADVANTAGE - The porous material uses a cross-linking agent to cross-link graphene and chitosan to prepare a hemostatic material, which improves the mechanical strength of the chitosan polymer and improves the hemostatic performance and antibacterial effect of the hemostatic material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) porous material assembled based on graphene oxide and chitosan molecule, is prepared by the method; and (2) hemostatic material, is prepared by the porous material based on graphene oxide and chitosan molecule assembly.
