Claim Text:
1. A nerve graft, comprising: a lyophobic substrate, wherein the lyophobic substrate is a silica gel substrate or a substrate coated with silica gel; a carbon nanotube film structure being a free-standing structure and comprising a plurality of carbon nanotubes substantially parallel to a surface of the carbon nanotube film structure, wherein the carbon nanotube film structure, having a thickness of about 0.5 nanometers to about 0.3 micrometers, is located on a surface of the lyophobic substrate and in direct contact with the lyophobic substrate, and the plurality of carbon nanotubes are single-walled carbon nanotubes; a protein layer directly located on a surface of the carbon nanotube film structure away from the lyophobic substrate, wherein a material of the protein layer comprises blood serum of a mammal, and the protein layer wraps each of the plurality of carbon nanotubes, and a thickness of the protein layer is from about 0.3 micrometers to about 2 micrometers; and a nerve network positioned on a surface of the protein layer away from the carbon nanotube film structure; wherein the nerve network comprises a plurality of nerve cells and a plurality of neurites branching from the nerve cells, and the plurality of neurites are connected between the plurality of nerve cells to form the nerve network.
