Claim Text:
1. A nerve graft, comprising: a carbon nanotube structure comprising at least one pressed carbon nanotube film comprising a plurality of carbon nanotubes combined and attracted to each other by van der Waals attractive force, an angle between a primary alignment direction of the carbon nanotubes and a surface of the carbon nanotube film is about 15 degrees, and the carbon nanotube structure is a free-standing structure; a hydrophilic layer, comprising a polar surface away from the carbon nanotube structure, the hydrophilic layer comprising a material selected from the group consisting of silicon dioxide, titanium dioxide, iron oxide, and a combination thereof, being directly located on a surface of the carbon nanotube structure, wherein the hydrophilic layer has a thickness in a range of from 1 nm to 50 nm; a nerve network having a polarity facing the polar surface of the hydrophilic layer, wherein a material of the polar surface comprises polyetherimide, the hydrophilic layer being located between the carbon nanotube structure and the nerve network, wherein the nerve network comprises a plurality of neurons connected with each other, and a polarity of the polar surface of the hydrophilic layer is attracted to the polarity of the nerve network.
