Title (EN) MULTI-SCALE BLOCK COPOLYMER COATING THAT INDUCES HYDROPHOBIC PROPERTIES
(FR) REVÊTEMENT DE COPOLYMÈRE SÉQUENCÉ À PLUSIEURS ÉCHELLES INDUISANT DES PROPRIÉTÉS HYDROPHOBES
Abstract:
(EN) Disclosed are methods of coating a surface of a substrate with a hydrophobic layer based on iterative steps of spin-coating, annealing, and etching of block copolymer thin films into multi-layer nano-meshes. Also disclosed are articles comprising a surface with a polymer coating, and methods of using the same as a self-cleaning surface.
(FR) L'invention concerne des procédés pour revêtir d'une couche hydrophobe une surface d'un substrat, basés sur des étapes itératives d'application par centrifugation, de recuit et de gravure de films minces de copolymère séquencé en des nano-mailles multicouches. L'invention concerne également des articles comprenant une surface ayant un revêtement polymère et leurs procédés d'utilisation en tant que surface autonettoyante.
