Abstract
A multi-layer stack includes: a substrate; a drain layer on a first side of the substrate, the drain layer having a sheet resistance of less than about 106 ohms per square; a heater layer on the drain layer; and a dielectric layer between the heater layer and the drain layer is disclosed. A transparency for a flying vehicle including the multi-layer stack and having the drain layer configured to be grounded to the flying vehicle, and a flying vehicle including the transparency is also disclosed.
Claims20
A multi-layer stack comprising:
- a transparent substrate;
- a drain layer on a first side of the substrate, the drain layer having a sheet resistance of less than about 106 ohms per square;
- a heater layer on the drain layer, the drain layer being between the heater layer and the substrate;
- a dielectric layer between the heater layer and the drain layer;
- a first topcoat on a second side of the substrate opposite to the first side;
- and
- a second topcoat on the heater layer, the second topcoat comprising a material selected from the group consisting of diamond like carbons polyurethanes polyacrylates polysiloxanes epoxies, silicon oxides, aluminum oxides, silicon oxycarbides, zirconium oxynitrides, cerium oxides, and combinations thereof.
