Methods for forming patterns on curved surfaces

摘要

Methods are disclosed by which two-dimensional and three-dimensional pattern layers may be formed on non-planar surfaces, including optical elements such as lenses with one or more cylindrical, spherical or aspheric surfaces. Patterns with features in the micro- and/or nano-size regime comprised of organic, inorganic or metallic materials may be formed by the methods described herein.

1. A method for fabricating a pattern on a compound curved surface, said method comprising:
a. forming a relief pattern on a stretchable surface to form a replication mold, b. coating a layer of curable polymer material on said stretchable surface, c. causing said coated stretchable surface to come in conformal compliant contact with a curved substrate d. exposing said curable polymer material to radiation to cause solidification of said polymer material, e. withdrawing said stretchable mold from contact with said substrate so as to leave the solidified polymer having a pattern complementary to that of the relief pattern of the stretchable replication mold as a layer on the surface of said substrate.
