  • Patent number: 11446918
    Abstract: A method of applying a pattern to a nonplanar surface. A stamp has a major surface with pattern elements having a lateral dimension of greater than 0 and less than about 5 microns. The major surface of the stamp has a functionalizing molecule with a functional group selected to chemically bind to the nonplanar surface. The stamp is positioned to initiate rolling contact with the nonplanar surface, and contacts the nonplanar surface to form a self-assembled monolayer (SAM) of the functionalizing material thereon and impart the arrangement of pattern elements thereto. The major surface of the stamp is translated with respect to the nonplanar surface such that: a contact pressure is controlled at an interface between the stamping surfaces and the nonplanar surface, and a contact force at the interface is allowed to vary while the stamping surfaces and the nonplanar surface are in contact with each other.

  • 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.
