Title
(EN) NONPLANAR PATTERNED NANOSTRUCTURED SURFACE AND PRINTING METHODS FOR MAKING THEREOF
(FR) SURFACE NANOSTRUCTURÉE NON PLANE À MOTIF ET PROCÉDÉS D'IMPRESSION POUR PRODUIRE CETTE SURFACE
Abstract
(EN)
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 of 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.
(FR)
L'invention concerne un procédé d'application d'un motif sur une surface non plane ayant un rayon de courbure. Un tampon pourvu d'une surface principale présente un motif en relief composé d'éléments de motif qui s'étendent à l'opposé d'une surface de base. Chaque élément de motif présente une surface d'estampage ayant une dimension latérale de 0 à 5 microns. Une encre appliquée sur la surface d'estampage contient une molécule de fonctionnalisation ayant un groupe fonctionnel qui se lie chimiquement à la surface non plane. Le tampon est positionné de manière à initier un contact de roulement entre la surface non plane et la surface principale du tampon. La surface d'estampage des éléments de motif entre en contact avec la surface non plane pour former une monocouche auto-assemblée du matériau de fonctionnalisation sur la surface non plane et transmettre l'arrangement des éléments de motif. Une position relative de la surface d'estampage est commandée par rapport à la surface non plane pendant que la surface principale du tampon entre en contact avec la surface non plane.
