Abstract
A mold for processing optical film includes a substrate, a copper oxide film, and a hydrophobic fluorinated self-assembled monolayer film. The substrate has a copper surface. The copper oxide film is formed on the copper surface. The hydrophobic fluorinated self-assembled monolayer film is formed on the surface of the copper oxide film. The mold provides easy release of the hydrophobic fluorinated self-assembled monolayer film.
Claims9
A method for manufacturing a mold for processing optical film, including steps of:
- providing a substrate in the form of a copper roller, the substrate having a copper surface, the copper surface comprising a plurality of microstructures, the microstructures defining a plurality of V-shaped recesses each extending parallel to an axis of the copper roller;
- oxidizing the copper surface of the substrate to form a copper oxide film;
- and
- dehydrating the copper oxide film with fluorinated fatty acid to form a fluorinated self-assembled monolayer film on a surface of the copper oxide film.
1 more element
A mold for processing optical film comprising:
- a substrate having a copper surface, a copper oxide film formed on the copper surface of the substrate, and a fluorinated self-assembled monolayer film formed on the copper oxide film, wherein the fluorinated self-assembled monolayer film is formed by dehydration with the copper oxide film and the fluorinated fatty acid.
