Abstract
A method and apparatus for depositing a coating on a substrate. A method of coating a substrate comprises evaporating a first reactant; introducing the evaporated reactant into a plasma; and depositing the first reactant on a surface of the substrate. This method may be used to deposit an electrically conductive, ultraviolet filter coating at high rate on a glass or polycarbonate substrate, for example. An apparatus for depositing a UV filter coating on a polymeric substrate comprises a plasma generator having an anode and a cathode to form a plasma, and a first inlet for introducing a first reactant into the plasma, the first reactant comprising an evaporated material that is deposited on the substrate by the plasma. Optionally, a nozzle can be utilized to provide a controlled delivery of the first reactant into the plasma.
