| (54) | Hydrophobic material and production process thereof |
| (57) A hydrophobic material includes a substrate, a fine uneven structure formed on a
surface of the substrate, and a hydrophobic molecule covering a surface of the fine
uneven structure. The fine uneven structure includes a petal-like structure formed
of an aggregate of a plurality of plate-like particles and a columnar structure formed
of columnar particles, in which a length from a surface of the substrate to the tip
of the columnar structure is longer than a length from the surface of the substrate
to the tip of the petal-like structure. The hydrophobic material is obtained by forming
a fine uneven structure including a petal-like structure formed of an aggregate of
a plurality of plate-like particles and a columnar structure formed of columnar particles
on a surface of a substrate, in which a length from a surface of the substrate to
a tip of the columnar structure is longer than a length from the surface of the substrate
to a tip of the petal-like structure, and covering a surface of the fine uneven structure
with a hydrophobic molecule.
