Abstract
A method of manufacturing a processed body having a hydrophobic and water-repellent surface, and a processed body having a hydrophobic and water-repellent surface. The method includes: a step of contacting a member made of a crystalline or semicrystalline polymer with a solvent in a solvent-contacting region; and a step of taking the member contacted with the solvent out of the solvent-contacting region and drying the member.
Claims7
A processed body comprising:
- a crystalline or semicrystalline polymer substrate;
- and
- a crystallite structure layer, wherein
- the crystallite structure layer comprises spherulites having an average particle diameter of 56 μm to 70 μm and nanostructures having an average particle diameter of 60 nm to 1500 nm that are present on a surface of the polymer substrate, and the average particle diameter of the nanostructures is smaller than the average particle diameter of the spherulites.
