(FR) NANOREVÊTEMENTS POUR ARTICLES
Abstract: front page image
(EN)A nano-coating comprises multiple alternating layers of a first layer comprising a first nanoparticle having an aspect ratio greater than or equal to 10 and having a positive or negative charge, and a second layer comprising a second nanoparticle having an aspect ratio greater than or equal to 10 and having a positive or negative charge opposite that of the first nanoparticle, wherein the nano-coating is disposed on a surface of a substrate. An article comprising the nano-coating, and a method of forming the nano-coating, are each disclosed.
(FR)L'invention concerne un nanorevêtement qui comprend de multiples couches alternées d'une première couche comprenant une première nanoparticule ayant un rapport d'aspect supérieur ou égal à 10 et ayant une charge positive ou négative, et une deuxième couche comprenant une deuxième nanoparticule ayant un rapport d'aspect supérieur ou égal à 10 et ayant une charge positive ou négative opposée à celle de la première nanoparticule, le nanorevêtement étant placé sur une surface d'un substrat. L'invention concerne un article comprenant le nanorevêtement, et un procédé de formation du nanorevêtement.
