Patent ID: 8230807

Claim:
A device for applying a coating comprising nanoparticles incorporated in a polymer matrix to a substrate through plasma activated deposition of a chemical vapor phase, which device comprises a reactor space provided with a carrier for a substrate, and at least first and second capacitively coupled plasma sources, for activating, respectively, first and second precursors, respectively, in first and second plasmas, wherein said first and second plasma sources are separated by a separating mesh; wherein said first plasma source comprises a first zone of the device which first zone is delimited by a top plate and the separating mesh, wherein the first plasma source further comprises a first electrode, which is in the form of a wire mesh, and which first electrode is positioned in between the top plate and the separating mesh and said first plasma source comprises a precursor inlet for a first precursor for said nanoparticles; wherein said second plasma source comprises a second zone of the device which zone is delimited by the separating mesh and a second electrode; and wherein said second plasma source comprises a precursor inlet for a second precursor for said polymer matrix; wherein the first electrode is structured for discharging on both the separating mesh and the top plate; and wherein the plasma sources are situated in the processing direction, such that said nanoparticles when formed in said first plasma are transported from said first plasma through the separating mesh to said second plasma where they are combined with the matrix-forming chemistry produced in the second plasma before being deposited on the substrate.
