Controllably providing a coating of nanoparticles on a conveyed substrate

Abstract

A spray system and method are described for controllably applying a coating of nanoparticles to a substrate. In particular, spray system arrangements are described that are configured to meet the goals of high quality nanoparticle deposition on a substrate with minimal waste of costly nanoparticle material. More particularly, a nanoparticle spray system is described herein that includes: a spray nozzle configured to emit a nanoparticle-laden spray flow; a conveyed substrate configured to be conveyed at a velocity; and a controller configured to operate in a feedback loop such that nanoparticles of the nanoparticle-laden spray flow are controllably deposited on a surface of the conveyed substrate.
