  • Patent number: 12157941
    Abstract: Barrier films including a (co)polymeric substrate, at least one dyad on the substrate, each dyad made of a (co)polymer layer and an oxide layer overlaying the (co)polymer layer, and an outer (co)polymer layer overlaying the dyads. Optionally, at least one outer oxide layer overlays the outer (co)polymer layer. The barrier films transmit visible light and transmits, at an incident light angle of at least one of 0°, 30°, 45°, 60°, or 75°, at most 70 percent of incident ultraviolet light at a wavelength range from at least 100 nanometers to 400 nanometers or in a wavelength range from at least 100 nm to 350 nm. The barrier films exhibit atomic oxygen degradation of less than 1×10?20 mg/atom. The barrier films may be applied to decorative objects or electronic devices, (e.g., light receiving or emitting devices, in a satellite or aircraft. Methods of making the barrier films also are disclosed.

  • Publication number: 20230212746
    Abstract: A system. The system may include a first zone into which a first precursor is introduced; a second zone into which a second precursor is introduced; a third zone between the first zone and the second zone and in which a reactive species is generated; a fourth zone between the first zone and the third zone; a fifth zone between the second zone and the third zone; wherein a process gas is introduced into the fourth zone and the fifth zone; wherein the reactive species and the first precursor is mixed in the fourth zone and the reactive species and the second precursor is mixed in the fifth zone; and a substrate transport mechanism.
