  • Publication number: 20100126873
    Abstract: 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.

  • Publication number: 20090260702
    Abstract: The present invention relates to a method for manufacturing a solid body having a superhydrophobic surface structure formed by using a surface treatment of a metal body, a replication process, and a polymer sticking phenomenon to increase efficiency of fluid transfer and prevent foreign materials from being accumulated in the tube, and a superhydrophobic fluid transfer tube using the method. The superhydrophobic fluid transfer tube includes a fluid guider and a solid body provided on a fluid contact surface of the fluid guider and has micrometer-scaled unevenness and nanometer-scaled protrusions.
