Abstract
There is disclosed a spray gun for spray deposition of 2D material onto substrate surfaces so as to allow for subsequent laser patterning or etching of said material into a metamaterial. The gun comprises: a housing 1 capable of accepting a propulsion device for propulsion of the material, wherein said housing 1 accommodates a reservoir for loading material to be deposited by spraying: and a nozzle 4 for directing the material to be sprayed by the gun. The nozzle 4 includes converging and diverging inner bore sections so as to enable propulsion of material at a supersonic speed.
