Title
(EN) SELF-CLEANING SURFACES
(FR) SURFACES AUTONETTOYANTES
Abstract
(EN)
A self-cleaning surface and methods of forming a self-cleaning surface that has one or more of hydrophobic characteristics and hydrophilic properties are provided. The self-cleaning surface includes a first layer formed from first nanoparticles that are applied on a substrate. A second layer of second nanoparticles that adhere to the first nanoparticles are then formed on the first layer.
(FR)
La présente invention a pour objet une surface autonettoyante et des procédés de formation d'une surface autonettoyante qui possède une ou plusieurs caractéristiques hydrophobes et/ou hydrophiles. La surface autonettoyante comprend une première couche formée à partir de premières nanoparticules qui sont appliquées sur un substrat. Une seconde couche de secondes nanoparticules qui adhèrent aux premières nanoparticules est ensuite formée sur la première couche.
