Metal Painting by Plasma Jet (Adv. Mater. Interfaces 24/2024)

Metal Printing In article 2400256, Daren J. Caruana and co-workers develop a single step method for depositing silver and copper tracks on a variety of dielectrics using an atmospheric pressure plasma jet. Particle free aqueous based metal salts are required as inks, which are reduced by the action of the plasma electrons and sintered. The resulting highly conductive and adhesive tracks may be deposited on glass, ceramics, polymeric materials, and even biological surfaces with zero damage to the substrates.
