Definitions
- the present invention relates to transparent conductive layers, in particular based on oxides, of great interest on glass substrate.
- ITO indium tin oxide
- SnO 2 F layers of fluorine-doped tin oxide.
- Such layers constitute electrodes in certain applications: flat lamps, electroluminescent glazing, electrochromic glazing, liquid crystal display screen, plasma screen, photovoltaic glazing, heated glasses.
- these transparent conductive layers do not have to be activated by a power-up.
- these transparent conductive layers are generally associated with an underlayer to improve the optical properties of a layer or a stack of transparent conductive layers on a glass substrate.
- EP 611 733 by PPG proposes a mixed gradient layer of silicon oxide and tin oxide to avoid the iridescence effects induced by the transparent conductive oxide layer.
- tin doped with fluorine proposes a variant of this underlayer for improving the color properties of a conductive transparent layer of fluorine-doped tin oxide.
- the precursors mentioned in this patent are on the other hand unusable on an industrial scale.
- SAINT-GOBAIN also has a know-how in this field: the patent FR 2,736,632 thus proposes a mixed sub-layer with a reverse index gradient of silicon oxide and tin oxide as anti-backing layer.
- a characterization test of this phenomenon consists of subjecting the glass and its electrode during for example 10 minutes to the joint action of fields electric of the order of 200 V for example, on both sides of the glass, and temperatures of 200 0 C. The action of an electric field at these temperatures induced for the duration of the test a total of electrical charges displaced from 1 to 8 mC / cm 2 according to the electrical resistivity values of the glass at the test temperature.
- delaminations are also observed in the case of curved glasses. These delaminations are undetectable by a man who is not of the profession if the glasses thus coated are not traversed by an electric current. On the other hand, in the case of applications where the glass thus coated is traversed by an electric current, as is the case for a heating glass for example, then the presence of these delaminations removes the functionality.
- the inventors have developed an underlayer connecting a glass substrate to a transparent conductive oxide layer considerably improving the adhesion of the latter, in particular under conditions of placing in the electric field of the assembly and relatively high temperatures, greater than 100, or even 150 0 C, or especially when the glass is formed (curved and / or tempered).

- An example is a mixed layer comprising SiO 2 grains mixed with SnO 2 grains.
- the continuous gradient of composition means a regular decrease in the proportion of SiO 2 grains compared to those of SnO 2, for example in the entire thickness of the mixed layer at increasing distance from the glass substrate.
