  • Patent number: 9790584
    Abstract: An apparatus and method for coating a substrate moved along a path of travel through the apparatus. A plasma source issues a plasma jet into which a first reagent is injected from a discharge orifice located upstream of the jet. A second reagent is injected into the jet from a discharge orifice located downstream of the jet. A controller is configured to regulate the flow of the first reagent according to a first set of parameters and regulate the flow of the second reagent according to a second set of parameters. As a result, the first and second reagents are applied to the substrate to form at least one layer of a coating on the substrate.

  • Publication number: 20170044340
    Abstract: Disclosed are optically transparent super-hydrophobic materials, and methods for making and using the same, that can include an optically transparent polymeric layer having a first surface and an opposing second surface. At least a portion of the first surface has been plasma-treated with oxygen and a fluorine containing compound. The treated surface includes nano- or micro-structures that are etched into the first surface and that are chemically modified with the fluorine containing compound. The nano- or micro-structures have a height to width aspect ratio of greater than 1, and a water contact angle of at least 150°. The optically transparent polymeric layer retains its optical transparency after said plasma-treatment. Due to their optical transparency, chemical and thermal robustness, weatherability, and self-cleaning performance, the super-hydrophobic materials disclosed are useful in high performing solar cell units in harsh semi-arid environments.
