Title: Method of making a microstructured coated article

Abstract: A method of making a polymer coating on a microstructured substrate. The method may be performed by vaporizing a liquid monomer or other pre-polymer composition and condensing the vaporized material onto a microstructured substrate, followed by curing. The resulting article may possess a coating that preserves the underlying microstructural feature profile. Such a profile-preserving polymer coating can be used to change or enhance the surface properties of the microstructured substrate while maintaining the function of the structure.
