A method of forming a polymer film includes dispensing a substrate and coating the substrate with a composition that is curable using actinic radiation. In an example, the method further includes exposing the composition to actinic radiation in presence of an atmosphere including 1 vol % to 37 vol % oxygen, whereby the surface of the composition forms an undulating morphology. In another example, the method further includes applying an oxygen-containing overlay over the composition, exposing the composition to actinic radiation through the oxygen-containing overlay, and removing the oxygen-containing overlay, whereby the surface of the composition forms an undulating morphology. |
