Title
(EN) PROCESS TO PREPARE A STRUCTURED ARTICLE USING A REMOVABLE PROTECTIVE LAYER AND STRUCTURED ARTICLE OBTAINED BY SAID PROCESS
(FR) PROCÉDÉ DE PRÉPARATION D'UN ARTICLE STRUCTURÉ À L'AIDE D'UNE COUCHE DE PROTECTION AMOVIBLE ET ARTICLE STRUCTURÉ OBTENU PAR LEDIT PROCÉDÉ
Abstract
(EN)
The present invention relates to a process for producing a structured article (A1M1) in which a material (M1) comprising at least one micro- and/or nanostructured surface (SU1) containing a plurality of micro-scale and/or nano-scale surface elements is covered with an at least partially cured coating layer (C2) to provide a composite (M1C2), said composite (M1C2) is attached to an object (A1) and the coating layer (C2) is at least partially peeled off to provide the structure article (A1M1). The present invention also relates to a composite (M1C2) in which the surface elements of the structured material (M1) are covered by a protective coating layer (C2).
(FR)
La présente invention concerne un procédé de production d'un article structuré (A1M1) dans lequel un matériau (M1) comprenant au moins une surface micro-et/ou nanostructurée (SU1) contenant une pluralité d'éléments de surface à l'échelle micrométrique et/ou nanométrique qui est recouverte d'une couche de revêtement au moins partiellement durcie (C2) pour fournir un composite (M1C2), ledit composite (M1C2) étant fixé à un objet (A1) et la couche de revêtement (C2) étant au moins partiellement décollée pour fournir l'article de structure (A1M1). La présente invention concerne également un composite (M1C2) dans lequel les éléments de surface du matériau structuré (M1) sont recouverts d'une couche de revêtement protecteur (C2).
