  • Publication number: 20210260901
    Abstract: A method of applying a pattern to a nonplanar surface with a radius of curvature. A stamp with a major surface has a relief pattern of pattern elements extending away from a base surface. Each pattern element has a stamping surface with a lateral dimension 0 to 5 microns. An ink applied on the stamping surface includes a functionalizing molecule with a functional group that chemically binds to the nonplanar surface. The stamp is positioned to initiate rolling contact between the nonplanar surface and the major surface of the stamp. The stamping surface of the pattern elements contacts the nonplanar surface to form a self-assembled monolayer of the functionalizing material on the nonplanar surface and impart the arrangement of pattern elements. A relative position of the stamping surface is controlled with respect to the nonplanar surface while the major surface of the stamp contacts the nonplanar surface.
