    摘要: 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.

    摘要: The present disclosure relates to abrasive articles including conformable coatings, e.g. a hydrophilic coating, and polishing systems therefrom. The present disclosure provides an abrasive article including a ceramic body having an abrading surface and an opposed second surface, wherein the abrading surface of the ceramic body includes a plurality of engineered features each having a base and a distal end opposite the base and the ceramic body has a Mohs hardness of at least 7.5; a conformable metal oxide coating adjacent to and conforming to the plurality of engineered features, wherein the conformable metal oxide coating includes a first surface; and a conformable polar organic-metallic coating in contact with the first surface of the conformable metal oxide coating, wherein the conformable polar organic-metallic coating includes a chemical compound having at least one metal and an organic moiety having at least one polar functional group.
