Abstract
The present application relates to a laminate, a method for preparing same and a use of the laminate. The present application can provide a method for forming a film, which comprises a self-assembled block copolymer, to have excellent uniformity in thickness even when the film is formed over a large area, a laminate comprising a polymer film formed by means of the method, and a use of same.
Claims8
A method for manufacturing a laminate, the laminate comprising a substrate and a polymer film, the method comprising:
- coating a coating liquid on a substrate at a coating speed of 10 mm/sec to 100 mm/sec using a coating means;
- annealing the coating liquid to form a polymer film,
- wherein the coating liquid comprising a block copolymer dissolved in a solvent having a boiling point in a range of 90° C. to 200° C.,
- wherein the coating speed is a moving speed of the substrate relative to the coating means, or a moving speed of the coating means relative to the substrate, and
- wherein the coating of the coating liquid is performed by a bar coating method.
