The invention relates to a heating element comprising a substrate () equipped with a thin-film multilayer, the thin-film multilayer comprising a film () suited to being heated, this film having a sheet resistance of between 20 and 200 &#x3a9;/square, the heating element also comprising two conductive collectors suited to being fed with electrical voltage, the film suited to being heated being a transparent electrically conductive oxide film and the film () suited to being heated not being machined and being electrically connected to the two conductive collectors, the film () suited to being heated having a thickness of between 50 nm and 300 nm. The invention allows a heating element, with a film suited to being heated that is simple to manufacture, to be easily installed in an electric vehicle or easily connected to the national grid.

Film-type heating element

A heating element including: (I) a substrate equipped with a thin-film multilayer, the thin-film multilayer including a heating film that has an electrical sheet resistance lying between 20 and 200 ohms per square, and two nonmetallic dielectric films located on either side of the heating film; and (II) two conductive collectors designed to receive a voltage, where the heating film is unpatterned, made of metal, and electrically connected to the two conductive collectors.

Heating element comprising films

The invention relates to a substrate (), especially a transparent glass substrate, equipped with a thin-film multilayer comprising, in alternation, 'n' metallic functional films (), in particular functional films based on silver or a metal alloy containing silver, and '(n+1)' antireflection coatings (), where n is an integer&#x2267;3, each antireflection coating comprising at least one antireflection film, so that each functional film () is located between two antireflection coatings (), characterized in that said multilayer comprises at least two high-refractive-index antireflection films (), each having a refractive index&#x2267;2.15 such that the antireflection coating () located under the first, starting from the substrate, functional film () and the antireflection coating located on the last, starting from the substrate, functional film each comprise at least one high-refractive-index antireflection film () and each antireflection coating () located between two functional films does not comprise a high-refractive-index film.

Substrate provided with a multilayer coating having thermal properties, in particular for production of a heated glazing unit

One subject of the invention is a material comprising a substrate coated on at least one portion of at least one of its faces with a stack comprising a photocatalytic layer, the geometrical thickness of which is between 2 and 30 nm, and at least one pair of respectively high and low refractive index layers positioned underneath said photocatalytic layer so that in the or each pair, the or each high refractive index layer is closest to the substrate, said material being such that the optical thickness, for a wavelength of 350 nm, of the or each high refractive index layer, except the photocatalytic layer, is between 170 and 300 nm and the optical thickness, for a wavelength of 350 nm, of the or each low refractive index layer is between 30 and 90 nm.
