- TITLE PROCESS FOR DEPOSITING METAL NANOPARTICLES ON A TEXTILE TABLECLOTH BY PHOTOCATALYSIS AND CORRESPONDING TEXTILE TABLECLOTH
- the invention relates to the field of deposits of metal particles on a support by photocatalysis. More specifically, the invention relates to a method for depositing metal particles by photocatalysis on a textile support, as well as the textile support thus coated.
- the photodeposition of metallic particles, such as particles of silver, gold, nickel or even platinum, on a substrate based on titanium dioxide (T1O 2 ) consists in particular of immersing the substrate in an aqueous or alcoholic solution containing an ionic precursor of the metal to be deposited, then in irradiating the assembly with a light source for a predefined time.
- the light source is generally placed at a distance from the support so as to provide illumination of the area to be coated.
- the resulting system is relatively bulky.
- the multiplication of light sources would make it possible to reduce distances, but also requires complex adjustment of the position of these light sources to ensure uniform illumination of the entire surface to be covered.
- the present invention therefore proposes an alternative solution for photodepositing metal particles, easier to implement, less bulky, which does not require complex adjustment steps.
- the solution of the present invention allows in particular full or localized deposition of metal particles on the surface of a support, regardless of the size of the support, but also the deposition of different types of metal particles on the same support.
- the invention therefore proposes a method for depositing metal particles on a textile support, comprising:
- the textile web o bringing at least one textile web based on side-emitting optical fibers into contact with a solution containing at least one ionic precursor of a metal to be deposited, the textile web being formed of optical fibers in a chain and / or in weft woven with binding yarns in warp and / or weft, each of the optical fibers exhibiting invasive alterations along the fiber and allowing the emission of light propagating in the fiber at the level of these alterations, the textile web being coated on all or part of its surfaces with a layer of semiconductor particles exhibiting photocatalytic properties, the textile web and the solution being contained in a volume of a reactor, the volume being devoid of / free of oxygen;
- the illumination of the textile web by at least one light source connected to all or part of the free ends of the optical fibers, said light source generating light radiation suitable for activating the photocatalysis of the semiconductor inducing the deposition of metal particles on the coating layer.
- the light radiation is emitted by the support itself.
- the textile web constitutes both the support to be covered with metal particles and a light guide bringing the light radiation as close as possible to the areas to be covered with metal particles. The irradiation of the semiconductor particles is therefore optimal.
- the textile web can equally well be produced in the form of a fabric, of a knit or of a braid.
- the textile web is preferably in the form of a fabric composed of warp threads and weft threads arranged in predetermined patterns depending on the applications.
- the method can comprise:
- the free ends of all the optical fibers of the textile web simultaneously receive said light radiation inducing deposition of metal particles on all of the surfaces of the textile web in contact with the solution.
- the photocatalytic layer covers the entire textile web and the metal particles are distributed evenly over this layer.
- the light radiation can be injected simultaneously at the ends of a group of optical fibers of the textile web, inducing the localized deposition of the metal particles on the textile web.
- the metal particles are deposited only on the areas of the photocatalytic layer which are illuminated by the optical fibers.
- a textile web is thus obtained having areas covered with metal particles and non-covered areas.
- the textile web may have a first zone covered with metal particles of a first type, and a second zone covered with metal particles of a second type.
- the method can comprise a first localized deposit of a first type of metal particles, this first deposit consisting in carrying out the steps of the method described above by illuminating a first group of optical fibers, then a second localized deposition of a second type of metal particles. This second deposit comprising in particular, after the deposit of the first type of metal particles:
- the second localized deposit does not require a complete cleaning of the reactor volume. It suffices in particular to stop the illumination of the first group of optical fibers, to inject the precursor of the second type of metal into the solvent, to carry out the homogenization of the solution, then to inject light radiation, also suitable for activating the photocatalysis of the semiconductor, in a second group of optical fibers distinct from the first group in order to induce the deposition of the metal particles of the second type on the irradiated zones of the textile web.
- the photocatalytic layer is made of a material chosen from the group comprising titanium dioxide, zinc oxide, zirconium dioxide, and cadmium sulfide.
- the photocatalytic layer is based on titanium dioxide (TiC).

It will be noted that in these figures, the same references designate identical or similar elements and the different structures are not to scale. Furthermore, only the elements essential for understanding the invention are shown in these figures for reasons of clarity.
- the method of depositing metal particles of the invention therefore consists in depositing metal particles by photocatalysis on a textile web based on woven optical fibers covered with a semiconductor layer having photocatalytic properties, such as T1O2.
- a semiconductor layer having photocatalytic properties such as T1O2.
- UV radiation under ultraviolet (UV) radiation, a reduction reaction of the ions of the metal on the photocatalyst takes place, metal particles are formed and these metal particles attach themselves to the T1O2 layer.
- FIG. 1 Such a textile web according to one embodiment is illustrated in FIG. 1.
- This textile web 1 therefore incorporates optical fibers 2 with lateral emission arranged in a warp and / or weft, and woven with binding threads 3 arranged in a warp and / or in frame.
- the free ends 6 of the optical fibers are intended to be connected to a light source 7.
- the optical fibers can be based on a polymer and the binding yarns can be made of polyester.
- the optical fibers are distributed evenly in a plane, parallel to each other.
- These optical fibers also exhibit invasive alterations on their outer surface, such that the light propagating in the fiber escapes from the fiber through these alterations.
- These alterations can be carried out in various ways, including for example surface treatments adapted to generate surface modifications of the optical fibers, namely modifications of the geometry and / or of the physicochemical properties of the surface of the optical fibers.
- These alterations allowing the light propagating in the fiber to leave the latter at the level of these alterations can for example be obtained by sandblasting, chemical etching or laser treatment processes.
- these alterations can be distributed progressively over the surface of the optical fibers so as to ensure uniform illumination.
- the surface density or the dimension of the alterations can thus vary from zone to zone. the other from the tablecloth.
- the surface density of the alterations may be low, while it increases the further one moves away from the source.
- the distribution of the alterations along the optical fibers is adapted to ensure a homogeneous lateral emission over the entire length of the optical fibers.
- different weaving techniques can be used. For example, it is possible to carry out a weaving showing the optical fibers on only one side of the textile web, that is to say that the textile web has only one luminous face. It is also possible to achieve a weaving showing the optical fibers on both sides of the textile web, that is to say that the textile web has two luminous faces.
- the textile web is further coated with a layer based on semiconductor particles exhibiting photocatalytic properties, such as for example particles of titanium dioxide (TiC).
- the photocatalytic particles can be attached in different ways to the textile web and can form a layer covering all of the textile web or only specific areas, for example on only one side of the textile web.
- the photocatalytic coating layer can in particular be attached, before weaving, to one or more components of the textile web, namely to the binding yarns and / or the optical fibers.
- the photocatalytic layer can also be deposited after weaving on the two components of the fabric, and in particular either on all the fabric formed by the optical fibers associated with the binding threads, or on specific areas of the fabric. Further, the photocatalytic layer can be deposited in various ways, for example by bathing, padding, emulsion, spraying, printing, encapsulation, electrodeposition, etc.
- the coating layer 4 containing the photocatalytic particles is attached to the binding yarns 3 before weaving with the optical fibers 2 exhibiting alterations 5.
- the layer of coating 4 containing the photocatalytic particles is attached to the optical fibers 2 before weaving with the binding yarns 3.
- the coating layer 4 containing the photocatalytic particles is attached, after weaving, to the fabric formed by the optical fibers 2 woven with the binding threads 3.
- a silica-based protective layer prior to the deposition of the photocatalytic layer.
- Such a protective layer is advantageous in the case where the textile web is intended for use in a medium provided with oxygen. However, when the textile web is intended to be integrated in an oxygen-free environment, it is preferable to omit such a protective layer. Indeed, the absence of the layer of silica (S1O2) allows a deposition of metallic particles of smaller nanometric size.
- the free ends 6 of the optical fibers 2 are connected to one or more light sources 7 configured to each generate a light radiation suitable for causing photocatalysis of the TiC layer. These free ends 6 may or may not be grouped together in bundles via ferrules.
- the optical fibers 2 are grouped into separate bundles 21, 22, 23 via ferrules 81, 82, 83, and are connected to separate light sources 71, 72, 73. It is thus possible to choose groups of optical fibers to be illuminated and therefore the areas of the textile web which will be covered with metal particles.
- all beams 21, 22, 23 can be illuminated simultaneously, and as shown in Figure 6, it is possible to illuminate a single beam 22.
- the light sources can be of different types, and in particular be in the form of light-emitting diodes.
- the light sources 7 are configured to generate light radiation of wavelength suitable for the photocatalysis of semiconductor particles.
- T1O2 particles we will favor ultraviolet radiation of wavelength in the range 300nm to 400nm.
- the light intensity applied is at least 0.1 mW / cm 2 .
- Preparation 100 of a solvent 90 first of all, a solution based on water and / or alcohol is prepared to act as a solvent into which the precursor of the metal to be deposited will be injected.
- this solution can be, for example, glycerol, or a hydroalcoholic solution.
- this solution 90 is then placed in a volume of a reactor 9, for example a two-phase cylindrical reactor (liquid / gas) incorporating a bubbling system 91 of inert gas in the vertical direction or a bubbling system via a tube inserted into the reactor.
- the bubbling system will notably make it possible to remove the oxygen (O2) contained in the volume before the injection of the precursors.
- O2 oxygen
- any other volume suitable for the implementation of the method can be used.
- a single-phase (liquid) reactor can be used. In this case, to eliminate I ⁇ 2, it is possible to carry out a photocatalytic reaction so as to consume I ⁇ 2, then a rise in temperature to degas.
- the reactor 9 can also integrate a mechanical system, such as a stirrer 92, which will make it possible to homogenize the precursor injected into the solvent.

- the free ends of the optical fibers 2 of the textile web 1 are grouped into a bundle 20, via a ferrule 80 or any other suitable connector.
- the reactor is then sealed, with the ferrule 80 passing through the reactor cover 93 to allow connection of the beam to a light source 70, such as an LED, external to the reactor 9 and configured to generate UV radiation.
- a light source 70 such as an LED
- Deoxygenation 103 of the volume of the reactor in order to remove the oxygen (O2) present in the volume of the reactor, an inert gas bubbling, such as argon or nitrogen, is carried out, via the bubbling system 91 for example. This step must be carried out before the injection of the metal precursor.
- Injection 104 of the metal precursors in the absence of light and oxygen, and at room temperature (between 20 ° C and 35 ° C for example), a predefined volume of a metal precursor solution 94 is injected into the reactor.
- the precursor solution can be based on chloroplatinic acid (PhPtCl ô ), at the concentration necessary to photo-deposit a determined quantity of metal on the titanium dioxide.
- the precursor solution can be based on silver nitrate (AgNCh), and for gold deposition, the precursor solution can be based on chlorauric acid (HAuCU).
- AgNCh silver nitrate
- HAuCU chlorauric acid
- the amount of precursor is defined as a function of the percentage of metal particles to be deposited on the surface of the support.
- Homogenization 105 of the precursor in the solvent after injection, the solution contained in the volume of the reactor is homogenized.
- the homogenization can be carried out via the inert gas bubbling system 91. In practice, for example, at least thirty minutes are waited under bubbling inert gas to ensure good mixing of the liquid medium in order to avoid deposition by conglomerates and on only part of the textile web. Agitation can also be done via a stirrer 92 to reduce the homogenization time.
- Photo-deposition reaction 106 after homogenization, the textile web is illuminated by injection via the light source 70 of UV radiation into the optical fibers 2. The metal particles are thus deposited by photo-deposition on the T1O2 layer. illuminated by optical fibers.
- UV radiation with a wavelength between 300nm and 400nm may be appropriate.
- the amount of metal particles deposited on the T1O2 layer relative to the amount of T1O2 particles present on the textile web can advantageously be of the order of 0.1% to 10%.
- the use of a luminous textile as a support for the photocatalytic semiconductor optimizes the irradiation of the photocatalytic particles.
- all of the metallic precursor present in the solution is deposited in the form of metallic particles on the textile web.
- the solution of the invention is therefore a deposition process which does not induce waste of metal particles, which therefore does not require reprocessing of the effluent to recover the metal particles, and which therefore makes it possible to reduce manufacturing costs. .
- the textile web generally has no aggregate and the deposited metal particles can therefore all be active.
- Photo-deposition on the whole of one side of the textile web the textile web is woven so as to allow illumination by the optical fibers of only one of the two faces of the web. All optical fibers are connected to a light source and simultaneously receive UV radiation. During the photocatalysis reaction, the metal particles are therefore deposited on the only surface illuminated by the optical fibers.

- the right figure illustrates the textile web after photocatalysis.
- the metal particles are deposited on the entire surface of one side of the textile web 1.
- the textile web is woven so as to allow illumination by the optical fibers of one or both sides of the web.

- the metal particles of a second type are fixed on the zones corresponding to the optical fibers 2b. It is thus possible to envisage multifunction textile webs.
- Such metallized textile webs can be used in various applications, such as the production of hydrogen (3 ⁇ 4).
- the textile webs can in particular be placed in a volume of a pressurized reactor.
- one or more textile webs 1 on which are deposited particles of platinum for example are placed in a reactor 9, the optical fibers are connected to light sources, and the textile webs are immersed.
- an alcoholic solution contained in the volume of the reactor can be glycerol (synthetic or natural).
- the volume of the reactor is also maintained at a certain temperature, for example 40 ° C.
- An inert gas such as argon or nitrogen is introduced into the volume, for example by a bubbling system 91, which also makes it possible to detach the hydrogen bubbles formed on the surfaces of the textile layers.
