Definitions
- the present invention relates to a transparent or translucent substrate, particularly of the type requiring a high optical quality: glazing for transport vehicle, building, ophthalmic glass, display system screen (television, computer, telephone), road sign,
- the case of the translucent substrate is represented by applications of glass substrate or thick plastic material, and / or printed and / or textured surface, including diffusing glazing, lighting systems, functionalized glazings of Electrochromic type ...
- the substrate of the invention is a glass such as silico-soda-lime or other composition, or a transparent plastic material: polycarbonate, polypropylene, poly (methyl methacrylate), ethylene / vinyl acetate copolymer, polyethylene terephthalate or butylene), polyurethane, polyvinyl butyral, or cycloolefin copolymer, that is to say, in particular, ethylene-norbornene copolymer or copolymer of ethylene and cyclopentadiene, ionomer resin (ethylene / (meth) acrylic acid copolymer neutralized with polyamine ...), unsaturated polyester, ethylene / vinyl acetate copolymer ...
- the invention aims in particular at providing a transparent substrate having a layer that provides it durably with various functions, individually or in combination, to an adjustable degree, controllable, while preserving the essential of the optical quality and the original transparency.
- a protection of the layer is necessary against for example the heat, the humidity, the mechanical aggression (scratches %), chemical, the presence of oxygen, UV ...
- protective layers of the substrate itself especially with respect to UV, mechanical aggression, are often also necessary, especially when the substrate is a polymer such as polycarbonate.
- Known protective layers are, for example, hard and thermally stable inorganic glasses, consisting for example of oxides and / or nitrides, among which may be mentioned SiO 2 , TiO 2, etc.
- inorganic glass layers can be prepared by different techniques: lacquers, sol-gel, plasma-assisted chemical vapor deposition
- Preferred Chemical Vapor Deposition Preferred Chemical Vapor Deposition
- Lacquer techniques, sol-gel are not without problems: poor resistance to diffusion of oxygen or water, poor mechanical strength, difficulty in multi-layers and thus meet various corresponding features.
- organic molecules degrade at a relatively low temperature and require particularly mild transfer conditions.
- the subject of the invention is a process for functionalizing a transparent or translucent substrate by forming a layer, which is distinguished by the fact that it comprises the steps of evaporating on the substrate at least one type of organic or organometallic molecule of functionalization, - simultaneously with the plasma-enhanced chemical vapor phase deposition of an inorganic glass matrix forming part of the layer.
- An organic molecule here comprises C, H, O, N, S, P, halogen atoms, an organometallic molecule furthermore comprises metal atoms such as Al, Ti, Mg, Si, etc. It is capable of exhibiting all types of usual bonds in organic molecules, in particular carbon-carbon single bonds sp3, carbon-carbon double bonds, benzene ring ... It is important that the vapor pressure of the functionalization molecule (s) at the evaporation temperature is sufficiently high so that at the pressure at which the deposition is carried out, sufficient flux is obtained on the substrate. Typically these vapor pressures vary between 1 and 1000 Pa depending on the molecule. An increase in this vapor pressure may result from the substitution of certain atoms or groups (H or CH 3 ) of the organic molecule by F atoms for example.
- the molecule can be adapted, transformed to incorporate links or groups to promote grafting in the matrix.
- the matrix consists of an inorganic glass as defined above.
- SiO x matrix by which is meant a network of crosslinked chains consisting essentially of atoms Si and O, but also C, H, N for example, in lesser proportion.
- This matrix is formed by a plasma-assisted chemical vapor deposition (PECVD): gaseous silicon precursors such as hexamethyldisiloxane, (HMDSO), tetramethyldisiloxane (TMDSO), tetraethoxysilane (TEOS), tetramethoxysilane (TMOS) are projected on the substrate under an argon-oxygen plasma for example.
- the precursors are thus polymerized / crosslinked.
- the inventors have found that the vapor condensation of various organic and / or organometallic molecules on the substrate, during the plasma polymerization of the inorganic glass matrix, makes it possible to incorporate in it derivatives of these organic molecules and / or organometallic able to provide various functions, in excellent conditions of protection by the matrix, so durability.
- the method of the invention allows the easy integration of different functionalities, because of the ease of flow control that is inherent to it. It allows in particular the mixing of different functional molecules (for example different colors) in the same layer, possibly in combination with stabilizers of one or more functional molecules or matrix.
- the method of the invention also facilitates the preparation of stacks of different layers including: one or more "pure” matrix layers with an oxygen barrier function, with water, protection against the diffusion of various chemical compounds,
- the vapor pressure can be modified by varying the evaporation temperature, knowing that certain molecules degrade from a given temperature that must not be exceeded.
- the flow at a given temperature depends on the geometry of the injection system and the surface of the evaporator.
- the temperature of the substrate is a parameter of the process of the invention which makes it possible to vary the blur of the product obtained. This temperature is both greater than and less than the melting temperature of the organic or organometallic molecules incorporated. When a weak blur is wanted, which is generally the case of glazing, the temperature of the substrate during the deposition must be sufficiently high.
- the vapor of each organic / organometallic molecule is heated, between its creation and its entry in contact with the substrate, so that its temperature increases when it is in motion, in particular metal pipes. .
- This measure facilitates the desired flow of steam.
- the subject of the invention is also a transparent substrate with a functional layer prepared according to the method described above, in which the function provided by an organic or organometallic molecule is a coloration function, a reflection of visible light variable with angle, electrical conductivity, infrared absorption or reflection, UV absorption or reflection, photochromic, thermochromic, electrochromic, electroluminescence, phosphorescence, fluorescence, anti-bacterial, photocatalytic, fungicide, odor absorber or emitter, anti-tobacco, hydrophilic or hydrophobicity.

- the pressure in the chamber during the deposition is 2 Pa, usually between 1 and 10 Pa.
- the organic molecule is 1,4-di (butylamino) anthraquinone (CAS 17354-14-2).
- the table below shows the deposition time of the various constituents, argon, oxygen and HMDSO flow rates in sccm (standard cubic centimeter per minute), and the microwave power (kW).
- the substrate is heated and maintained at 95 ° C during deposition, the melting point of 1,4-di (butylamino) anthraquinone being 120-122 ° C.
- the vapor pressure of this molecule varies between 1 and 15 Pa, which corresponds with the injection and evaporation system given to a flux varying between about 0.1 and 5 sccm.
- the light transmittance of 595 nm wavelength decreases from 87 to 66%.
- the deposited layer gives a blue color to the glazing all the more marked as the temperature of the evaporator increases.
- the blur of this window is at most 0.25%
- the 1,4 - di (butylamino) anthraquinone molecule is replaced by pyrene (C.A.S. 129-00-0).
- This molecule has an absorption peak around 325 nm in solution in cyclohexane and fluorescence peak (excitation length 317 nm) around 400 nm.
- the pyrene has a vapor pressure of about 100 Pa at 175 ° C (L5 Deposition), 200 Pa at 190 ° C (L4 Depot) and a vapor pressure of about 300 Pa at 200 ° C. ° C (deposit L3), which corresponds with the injection and evaporation system given to a flow of about 150, 500 and 1250 sccm respectively.
- the optical density of the three substrates with their layer is measured relative to that of a substrate provided with a layer without an organic molecule.
- a peak around 330 nm is observed whose intensity increases with the flow of the molecule, indicating a growing amount of organic molecule integrated in the layer.
- Figure 1 shows a fluorescence spectrum of the L4 deposition layer at the excitation wavelength of 317 nm.
- the fluorescence emission is expressed on a decimal logarithmic scale, as a function of the wavelength (nm).
- a peak centered around 400 nm is observed showing that the substrate with the molecule has fluorescent properties.
- Example 1 is reproduced by interposing between the deposition of the organic layer and that of the protective layer (see table) a step of integrating the pyrene according to the preceding example.
- the resulting layer has a green color
- Example 1 is repeated, replacing in the evaporator the 1,4-di (butylamino) -anthraquinone with 2- (2H-benzotriazol-2-yl) -4,6-bis (1,1-dimethylpropyl) phenol marketed by Ciba-Geigy company under the registered trademark TINUVIN 328.
- the evaporator is at a temperature of 213 ° C.
- Figure 2 shows the actual transmission (ie with subtraction of that of the layer without organic molecule), expressed in%, as a function of the wavelength in nm. It is found that UV absorption functionality is provided by the molecule at the layer.
- Example 1 is reproduced by varying the temperature of the substrate. At each test, the veil is measured.
- the web can therefore be controlled as a function of the substrate temperature during the deposition.
