▎ 摘　　要

NOVELTY - Three-dimensional graphene-collagen composite support comprises three-dimensional graphene support, and collagen fibers are bonded to the surface of the three-dimensional graphene support. The three-dimensional graphene-collagen composite support has three-dimensional porous structure. The pores in the three-dimensional porous structure having pore size is larger than 1 mu m and smaller than 100 mu m. USE - Used as three-dimensional graphene-collagen composite support. ADVANTAGE - The support: has simple preparation method, low cost, promotes the proliferation and differentiation of neural stem cells. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (1) preparing three-dimensional graphene-collagen composite support, providing three-dimensional graphene support, and setting the support in the threedimensional graphene strength is 5-10 kV of high voltage electrostatic field, and combining the collagen fiber with three-dimensional graphene support surface under the action of electrostatic field, forming three-dimensional graphene-collagen composite support, the three-dimensional graphene-collagen composite support has threedimensional porous structure, the pore diameter of the hole contained in the three-dimensional porous structure is greater than 1 mu m and less than 100 mu m, the porosity is greater than 98% and the diameter of the collagen fiber is more than 10 nm but less than 10 mu m; and (2) use of three-dimensional graphene-collagen composite support for cells comprising neural stem cells, neural progenitor cells, mesenchymal stem cells, and fibroblasts.
