Definitions
- the present invention relates to substrates such as substrates made of glass, glass-ceramic material or plastic which have been provided with a coating with photocatalytic property to give them a so-called anti-soiling or self-cleaning function.
- An important application of these substrates relates to glazing, which can be of very diverse applications, from utility glazing to glazing used in household appliances, glazing for vehicles to glazing for buildings. It also applies to reflective glazing of the mirror type (home mirror or vehicle rear view mirror) and opaque glazing of the light type.
- the invention also applies, similarly, to non-transparent substrates, such as ceramic substrates or any other substrate which can in particular be used as an architectural material (metal, tiles, etc.). It preferably applies, whatever the nature of the substrate, to substantially planar or slightly curved substrates.
- Photocatalytic coatings have already been studied, in particular those based on titanium oxide crystallized in anatase form. Their ability to degrade dirt of organic origin or microorganisms under the effect of UV radiation is very interesting. They also often have a hydrophilic nature, which allows the evacuation of mineral soiling by spraying water or, for exterior glazing, by rain. This type of coating with anti-fouling, bactericidal and algicidal properties has already been described, in particular in patent WO 97/10186, which describes several methods of obtaining it. To exercise its anti-fouling function
- Ti0 2 must be at least partially crystallized in the atanase structure. Otherwise Ti0 2 is not functional and requires heat treatment after deposition in order to acquire the crystallographic structure which makes it effective. Thus, since Ti0 2 is deposited by a gas phase pyrolysis technique (CVD type) involving a high temperature, it spontaneously has the right structure. If it is deposited cold (room temperature), in particular by a vacuum deposition technique, it becomes functional only after a suitable heat treatment.
- CVD type gas phase pyrolysis technique
- the present invention aims to provide a solution for obtaining the good state of Ti0 2 without necessarily calling for a heating step.
- the present invention therefore firstly relates to a structure comprising a substrate carrying, on at least part of its surface, a layer with photocatalytic property, anti-fouling, based on titanium dioxide (Ti0 2 ) at least in part crystallized in its anatase form, characterized in that it comprises, immediately below at least one layer of Ti0 2 , an under-layer (SC) having a crystallographic structure having enabled assistance to crystallization by heteroepitaxial growth in the anatase form of the upper layer based on Ti0 2 , the photocatalytic property having been acquired without any heating step.
- Ti0 2 titanium dioxide
- SC under-layer
- sublayer (SC) is in particular based on a compound crystallized in a cubic or tetragonal system and having a mesh whose dimension is that of Ti0 2 crystallized in anatase form to within 8%, in particular to within 6% .
- the sublayer (SC) consists of ATi0 3 , A denoting barium or strontium.
- the thickness of the underlay (SC) is not critical. Mention may in particular be made of values between 10 and 100 nm for this thickness.
- the substrate consists, for example, of a plate, flat or with curved or curved faces, of monolithic or laminated glass, of glass-ceramic material or of a hard thermoplastic material, such as polycarbonate, or also of glass fibers or glass-ceramic, said plates or said fibers having, where appropriate, received at least one other layer functional before the application of the sublayer (SC) (in the case of more than one layer, we can also speak of stacking of layers).
- SC sublayer
- the applications of the plates have been mentioned above.
- fibers mention may be made of their application to the filtration of air or water, as well as bactericidal applications.
- At least one functional layer underlying the sublayer (SC) can be a layer which forms a barrier to the migration of alkalis from the glass or ceramic glass material. Such migration may result from the application of temperatures in excess of 600 C C.
- layers forming alkali-barrier are known, and there may be mentioned layers of Si0 2, SiOC, SiO x Ny, thickness of e.g. 'at least 50 will, as described in international PCT application WO 02/24971.
- At least one functional layer underlying the sublayer (SC) can be an optically functional layer (advantageously for adjusting the optics in reflection), a thermal control layer or a conductive layer.
- the layers with optical functionality are in particular anti-reflection layers, light radiation filtration, coloring, diffusing, etc. Mention may be made of the layers of Si0 2 , Si 3 N, Ti0 2 amorphous or crystallized and photocatalytic, Sn0 2 , ZnO.
- the thermal control layers are in particular the solar control layers, or the so-called low-emissivity layers.
- the conductive layers are in particular the heating, antenna or anti-static layers, among these layers, one can count the networks of conductive wires.
- substrates made of glass or glass-ceramic material in particular of plate type, having received a layer forming a barrier to the migration of alkalis from glass or glass-ceramic material, then a mono-, bi- or three-layer with optical functionality.
- the Ti0 2- based layer consists of
- the Ti0 2 layer was deposited at room temperature by sputtering under vacuum, if necessary assisted by magnetic field (magnetron) and / or ion beam; - the sublayer (SC) was deposited at room temperature by cathodic sputtering under vacuum, if necessary assisted by magnetic field and / or ion beam; ATi0 3 was deposited at room temperature by cathode sputtering under vacuum, if necessary assisted by magnetic field and / or ion beam, " with the use of ceramic targets chosen from ATi0 3 , ATi0 3 _ x with 0 ⁇ x ⁇ 3 , and ATi; the power supply being a radiofrequency power supply and the atmosphere of the sputtering enclosure containing only argon when ATi0 3 is used as target; the power supply being a power supply direct or alternating current and the reactive atmosphere of the sputtering enclosure containing oxygen and argon in the case of the use of ATi or ATi0 3 - x as target; the layer
- the layer of Ti0 2 can be coated with at least one over-layer of a material which does not disturb the anti-fouling function of the layer of Ti0 2 , such as Si0 2 .
- the layers intended to be in contact with the atmosphere in the finished structure are, depending on the case, hydrophilic or hydrophobic layers.
- the present invention also relates to the application of ATi0 3 to the constitution of an assisting layer for crystallization in the anatase form by heteroepitaxial growth of an upper layer based on optionally doped Ti0 2 , A denoting barium or strontium.
- the present invention also relates to a method of manufacturing a structure as defined above, characterized in that one deposits on a substrate of glass or glass-ceramic material or hard plastic material of polycarbonate type, plate type, or on glass or glass-ceramic fibers, an ATi0 3 sublayer, A representing barium or strontium, then a layer of Ti0 2 possibly doped, at least one overlay of a material which does not disturb not the anti-fouling function of the Ti0 2 layer which can then be deposited if necessary on the latter.
- the deposition of the ATi0 sublayer (SC) and that of the Ti0 2 layer can be carried out successively at room temperature by sputtering, under vacuum, if necessary assisted by magnetic field and / or ion beam, in the same enclosure, the targets used for the deposition of said sublayer being chosen from ATi0 3 , ATi0 3 - x with 0 ⁇ x ⁇ 3, and ATi, the supply being a radiofrequency supply and the atmosphere of the sputtering enclosure containing only argon when using ATi0 3 as a target; the power supply being a DC or AC power supply and the reactive atmosphere of the sputtering enclosure containing oxygen and argon, in the case of the use of ATi or ATi0 3 - x as target; and the target used for the deposition of Ti0 2 being Ti or TiO x , 0 ⁇ x ⁇ 2.
- the pressure can be between 10 "1 and 2.5 Pa.
- the supply is generally a direct current or alternating current supply, and the pressure is advantageously of the order of 1-3 Pa.
- the coating of a substrate is made of glass or glass-ceramic material
- SC undercoat

- the quenching or annealing operations can be carried out in cases where it is desired to improve the activity of the Ti0 2 layer.
- Such layers can be deposited by sputtering, optionally assisted by magnetic field, from known targets (for example Si: Al in the case of a layer of Si0 2 doped aluminum), advantageously in pulsed mode, AC (alternating current) or DC (direct current), under a pressure of 10 "1 to 1 Pa, and under argon and oxygen gas.
- targets for example Si: Al in the case of a layer of Si0 2 doped aluminum
