  • CONDUCTIVE LIQUID FORMULATIONS FOR ELECTROWETTING OPTICAL DEVICES
    Publication number: 20240168280
    Abstract: An electrowetting optical device includes a conductive liquid, a non-conductive liquid, and a substrate. The conductive liquid is buffered to an acidic pH. The conductive liquid and the non-conductive liquid are immiscible. The substrate includes a dielectric topcoat. The conductive liquid and the non-conductive liquid are in contact with the dielectric topcoat. The dielectric topcoat is a plasma-deposited organosilane precursor having the molecular formula SiOxCyHz.

  • Device for spraying coating material comprising a nozzle
    Publication number: 20020017239
    Abstract: This invention relates to a device for spraying coating material, which comprises a barrel inside which is defined a conduit for circulation of coating material, and a nozzle for shaping the jet of material intended to be mounted on this barrel. Magnetic coupling means are provided between the nozzle and the barrel. These means which are insulated from the conduit, may be formed by one or more magnets associated with a metallic ring. This allows easy and rapid assembly and dismantling of the nozzle on the end of the barrel.
