[0006] Le but de la présente invention est de proposer une encre de graphène dont les propriétés permettent un chauffage homogène, régulier et très performant. [0006] The aim of the present invention is to propose a graphene ink whose properties allow homogeneous, regular and very efficient heating.

[0007] Grâce à la présente invention, l'encre est destinée à être déposée sur un substrat en vue d'y appliquer une tension électrique de sorte à obtenir une augmentation de sa température. [0007] Thanks to the present invention, the ink is intended to be deposited on a substrate with a view to applying an electrical voltage to it so as to obtain an increase in its temperature.

[0008] Selon la présente invention, une encre comportant du graphène comporte en fraction massique, à l'état liquide, entre 20% et 40% de graphène, de 5% à 40% de résine acrylique et de 10% à 30% de solvants et 2 à 20% de dispersant, et à l'état solide, au moins 50% de graphène.

[0017] In the context of the application of an ink according to the present invention, on a multilayer electrothermal structure, or heating film, the heating ink comprises in mass fraction, in the liquid state, between 20% and 30% of graphene, from 10% to 30% of acrylic resin and from 10% to 20% of solvents and 5% to 15% of dispersant, and in the solid state, at least between 50% and 60% of graphene.

[0018] L'encre appliquée au film chauffant est agencée pour chauffer lorsqu'une tension électrique est appliquée. The ink applied to the heating film is arranged to heat when an electrical voltage is applied.

[0019] Le film chauffant devant être le plus fin possible inférieur à 0.4mm, le graphène est composé de particules de graphène d'une granulométrie de 1 à 3 microns, et dans certains cas, d'au moins deux types de particules à granulométrie différente, par exemple composé de particules de graphène d'une granulométrie de 1 à 3 microns et de particules de graphène d'une granulométrie de 7 à 10 microns. [0019] The heating film must be as thin as possible less than 0.4 mm, the graphene is composed of graphene particles with a particle size of 1 to 3 microns, and in certain cases, of at least two types of particles with particle size different, for example composed of graphene particles with a particle size of 1 to 3 microns and graphene particles with a particle size of 7 to 10 microns.

[0020] Dans une forme d'application, l'encre est agencée pour chauffer lorsqu'une tension électrique est appliquée par deux électrodes entourant toute ou partie de la surface de l'encre et disposées dans l'épaisseur de ladite encre. [0020] In one form of application, the ink is arranged to heat when an electrical voltage is applied by two electrodes surrounding all or part of the surface of the ink and arranged in the thickness of said ink.

[0021] L'encre peut être disposée dans sur un film connecté soit à un courant continu soit à un courant alternatif, sans pour autant avoir d'impact sur les performances de chauffe. [0021] The ink can be placed on a film connected either to direct current or to alternating current, without having any impact on the heating performance.

[0022] L'encre peut atteindre des températures atteignant environ 100°C mais dans notre exemple, la température est de préférence plafonnée de manière autorégulée à une température de 28°C. [0022] The ink can reach temperatures of around 100°C but in our example, the temperature is preferably capped in a self-regulated manner at a temperature of 28°C.

[0023] Il est à noter que les consommations électriques sont faibles et permettent, avec quelques dizaines de watts d'être efficaces en chauffe. [0023] It should be noted that the electrical consumption is low and allows, with a few tens of watts, to be efficient in heating.

[0024] L'encre de la présente invention peut être utilisée pour le chauffage domestique, notamment des bâtiments, pour les sols chauffants. The ink of the present invention can be used for domestic heating, in particular buildings, for heated floors.

[0025] Bien que l'invention ait été décrite selon un mode de réalisation particulier, elle n'y est nullement limitée, et des variantes peuvent y être apportées, ainsi que des combinaisons des variantes décrites concernant notamment l'épaisseur de l'encre sur un support sans pour autant sortir du cadre de la présente invention. [0025] Although the invention has been described according to a particular embodiment, it is in no way limited thereto, and variants can be made, as well as combinations of the variants described, particularly concerning the thickness of the ink. on a support without departing from the scope of the present invention.
