Patent ID: 8257630

Claim:
A method for fabricating a 3D (three-dimensional) structure, the method comprising: preparing a metal foil base by attaching a metal foil on an outer surface of a predetermined-shaped 3D structure; anodizing the metal foil base to form nano-scale holes on an outer surface of the metal foil base; coating a polymer material on the outer surface of the metal foil base to form the polymer material as a negative replica structure corresponding to the nano-scale holes of the metal foil base; forming an outer structure by covering an outer surface of the negative replica structure with an outer formation material; and removing the metal foil base from the negative replica structure and the outer formation material, wherein in attaching the metal foil on the surface of the predetermined-shaped 3D structure, the metal foil is sequentially pressed so as to not allow air to be introduced into an interfacial space.
