Claim One:
1. A method for forming a nerve graft, comprising: providing a carbon nanotube structure; evaporating or sputtering an inorganic material on a surface of the carbon nanotube structure to form a hydrophilic layer; soaking the hydrophilic layer with a polyamino acid solution or a polyetherimide solution to polarize a surface of the hydrophilic layer to a polar surface, wherein the soaking the hydrophilic layer with the polyamino acid solution or the polyetherimide solution comprises sub-steps of: providing a supporter; placing the carbon nanotube structure having the hydrophilic layer on a surface of the supporter; and soaking the hydrophilic layer on the carbon nanotube structure on the surface of the supporter with the polyamino acid solution or the polyetherimide solution to polarize a surface of the hydrophilic layer to a polar surface; and completely removing the polyamino acid solution or the polyetherimide solution from the polar surface; and seeding and culturing a plurality of neurons on the polar surface until adjacent neurons of the plurality of neurons are connected with each other, and the plurality of neurons form a nerve network.
