A method of modifying the wetting properties of the surface of a substrate, the method comprising the step of applying a first mold having an imprint forming surface to said substrate to form a first imprint thereon, said imprint forming surface being chosen to modify the wetting properties of the substrate surface.

Modification of surface wetting properties of a substrate

A method for forming hierarchical patterns on an article by nanoimprinting is disclosed. The method includes using a first mold to form a primary pattern on the article at a first temperature and a first pressure, the first temperature and the first pressure being able to reduce the elastic modulus of the article; and using a second mold to form a second pattern on the primary pattern at a second temperature that is below the article's glass transition temperature, the forming of the second pattern being at a second pressure.
