Abstract:
1. A superhydrophobic fluid transfer tube having a superhydrophobic surface structure, the superhydrophobic fluid transfer tube comprising: a fluid guider for guiding a fluid; a solid body that is provided on a fluid contact surface of the fluid guider and has micrometer-scaled unevenness and protrusions having nanometer-scaled diameters, wherein the solid body comprises a base provided on a fluid contact surface of the fluid guider and a surface structure having micrometer-scaled unevenness formed by a plurality of bunches formed by a plurality of adjacent protrusions that are formed on the base and have a nanometer-scaled diameter; and wherein a distance between the adjacent protrusions have nanometer-scaled diameters that are extremely short so that a van der Waals force attraction is generated between adjacent protrusions, and the micrometer-scaled unevenness are formed by the adjacent protrusions that are partly stuck to each other.
