摘要:
A method for fabricating a 3D (three-dimensional) structure is disclosed to provide hydrophobicity to a surface of a 3D structure by using a dipping method in which a predetermined-shaped structure is immersed in a molten metal solution. The method includes: immersing a predetermined-shaped structure in a molten metal solution to coat a molten metal material on the surface of the predetermined-shaped structure; anodizing a metal base coated with the molten metal material; coating a polymer material on an outer surface of the metal-coated base to form a negative replica structure; covering an outer surface of the negative replica structure with an outer formation material; and removing the metal-coated base from the negative replica structure and the outer formation material.

A method for fabricating a 3D (three-dimensional) structure such that the 3D structure has a surface with hydrophobicity by using a metal foil such as an aluminum foil is disclosed. The method includes 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; coating a polymer material on the outer surface of the metal foil base material to form a negative replica structure; 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.

The present invention relates to a manufacturing method of a three dimensional structure having a hydrophobic inner surface. The manufacturing method includes anodizing a three dimensional metal member and forming fine holes on an external surface of the metal member, forming a replica by coating a non-wetting polymer material on the outer surface of the metal member and forming the non-wetting polymer material to be a replication structure corresponding to the fine holes of the metal member, forming an exterior by surrounding the replication structure with an exterior forming material, and etching the metal member and eliminating the metal member from the replication structure and the exterior forming material.

The present invention relates to a three-dimensional structure manufacturing method for performing surface treatment processes, and a replication step to provide hydrophobicity on an external surface of the three-dimensional structure. In the manufacturing method, the hydrophobicity may be provided to the external surface of the three-dimensional structure, a high cost device required in the conventional MEMS process is not used, the manufacturing cost is reduced, and the manufacturing process is simplified. In addition, it has been difficult to provide the hydrophobicity on an external surface of a three-dimensional structure having a large surface due to a spatial limitation, but in the exemplary embodiment of the present invention, the hydrophobicity may be provided to the external surface of the three-dimensional structure having a large surface, such as a torpedo, a submarine, a ship, and a vehicle, without the spatial limitation.
