Nano-coatings for articles

摘要

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.
