Title
(EN) HIERARCHICAL SILICON NANOSTRUCTURES, METHODS OF MAKING, AND METHODS OF USE
(FR) NANOSTRUCTURES DE SILICIUM HIÉRARCHIQUES, PROCÉDÉS DE FABRICATION ET PROCÉDÉS D'UTILISATION
Abstract
(EN) Described herein are antireflective materials and methods of making antireflective materials. The material can include a plurality of hierarchical nanostructures on a base substrate and a total specular reflection of less than 3% at a wavelength of about 400nm to about 1100 nm. The material can have an etched polyimide layer disposed on the superior surface of the hierarchical nanostructures. The materials can also have superhydrophobic characteristics.
(FR) Sont décrits ici des matériaux antireflet et des procédés de fabrication de matériaux antireflet. Le matériau peut comprendre une pluralité de nanostructures hiérarchiques sur un substrat de base et une réflexion spéculaire totale inférieure à 3 % à une longueur d'onde d'environ 400 nm à environ 1 100 nm. Le matériau peut avoir une couche de polyimide gravée disposée sur la surface supérieure des nanostructures hiérarchiques. Les matériaux peuvent également présenter des caractéristiques superhydrophobes.
