This invention proposes a method for preparing a carbon nanotube array, characterized by the following steps: 1) providing two substrates; 2) etching and annealing a metal substrate, labeled as intermediate 1; 3) depositing carbon nanotubes (CNTs) on the surface of intermediate 1, gradually heating to cause intermediate 1 to undergo a second reconstruction, labeled as intermediate 2; 4) spin-coating a polymer solution onto the surface of intermediate 2 to form a polymer film, labeled as intermediate 3; 5) etching intermediate 3 to separate the polymer and carbon nanotubes from the metal substrate; 6) transferring the separated polymer and carbon nanotubes to a surface-insulating substrate to obtain a pre-prepared sample; 7) cleaning the pre-prepared sample to obtain the finished product. This invention prepares a horizontal carbon nanotube array with high density, high orientation, and high uniformity.
