Abstract
Certain example embodiments of this invention relate to articles including anticondensation coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anticondensation coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator/freezer doors, and/or the like.
Claims38
A skylight, comprising:
- first and second substantially parallel, spaced apart glass substrates;
- a plurality of spacers arranged to help maintain the first and second substrates in substantially parallel, spaced apart relation;
- an edge seal sealing together the first and second substrates;
- and
- an anticondensation coating provided on an exterior surface of the first substrate exposed to an environment external to the skylight, the anticondensation coating comprising the following thin-film layers deposited in the following order moving away from the first substrate:
- a silicon-inclusive barrier layer,
- a first silicon-inclusive contact layer,
- a layer comprising a transparent conductive oxide (TCO),
- a second silicon-inclusive contact layer, and
- a layer of zirconium oxide,
- wherein the anticondensation coating has a hemispherical emissivity of less than 0.23 and a sheet resistance of less than 30 ohms/square.
A coated article comprising:
- a coating supported by a glass substrate, wherein:
- the coating is an anticondensation coating comprising the following thin-film layers deposited in the following order moving away from the glass substrate:
- a silicon-inclusive barrier layer,
- a first silicon-inclusive contact layer,
- a layer comprising a transparent conductive oxide (TCO),
- a second silicon-inclusive contact layer, and
- a layer of zirconium oxide,
- the anticondensation coating is disposed on an exterior surface of the glass substrate such that the anticondensation coating is exposed to an external environment, and
- the anticondensation coating has a hemispherical emissivity of less than 0.23 and a sheet resistance of less than 30 ohms/square.
A method of making a coated article comprising a coating supported by a substrate, the method comprising:
- disposing a silicon-inclusive barrier layer on the substrate;
- disposing a first silicon-inclusive contact layer on the silicon-inclusive barrier layer;
- disposing a layer comprising a transparent conductive oxide (TCO) on the first silicon-inclusive contact layer;
- disposing a second silicon-inclusive contact layer on the TCO layer;
- and
- disposing a layer of zirconium oxide on the second silicon-inclusive contact layer,
- wherein the coating is an anticondensation coating to be located on an exterior surface of the substrate such that the anticondensation coating is exposed to an external environment, and
- wherein the anticondensation coating has a hemispherical emissivity of less than 0.23 and a sheet resistance of less than 30 ohms/square.
A coated article comprising
- a coating supported by a substrate, wherein:
- the coating is an anticondensation coating comprising the following thin-film layers moving away from the substrate:
- a silicon-inclusive barrier layer,
- a first silicon-inclusive contact layer,
- a layer comprising a transparent conductive oxide (TCO),
- a second silicon-inclusive contact layer, and
- a layer comprising zirconium oxide,
- wherein the anticondensation coating is disposed on an exterior surface of the glass substrate such that the anticondensation coating is to be exposed to an external environment, and
- the anticondensation coating has a hemispherical emissivity of less than 0.23 and a sheet resistance of less than 30 ohms/square.
