Innovative printed materials for a sustainable future
GTSA prints inks from innovative materials (including Graphene) on films. These films are used in industrial applications that contribute to the energy transition.
Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a regular hexagonal structure. Its experimental isolation was achieved in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester. This scientific breakthrough earned them the Nobel Prize in Physics in 2010.
Graphene has exceptional physical and chemical properties that surpass those of conventional materials. In terms of electron transport, it has extremely high charge carrier mobility, reaching around 200,000 cm²/V.s at room temperature, more than 100 times that of silicon (≈ 1,400 cm²/V.s), making it a leading candidate for next-generation electronic devices.
Its thermal conductivity is equally remarkable, with a value of up to 5,000 W/m.K, far surpassing copper (≈ 400 W/m.K), making it relevant for thermal management applications.
From a mechanical point of view, Graphene boasts a tensile strength up to 200 times that of steel, while retaining exceptional flexibility and lightness.
Its extraordinary properties are only fully apparent in the context of the Graphene atomic monolayer. The industrial production of "monolayer" Graphene remains a considerable challenge due to several obstacles, including high manufacturing costs and processing constraints.
Current synthesis methods, such as chemical vapor deposition (CVD), require sophisticated infrastructures and a controlled environment, thus considerably increasing production costs. In addition, its integration into functional systems poses problems of adhesion to substrates and compatibility with conventional materials.
These limitations, combined with prohibitive costs, currently hinder its large-scale industrialization and restrict its use to specific applications.
The solution from GRAPHENATON Technologies SA to overcome these obstacles lies in the use of Graphene inks. These formulations, consisting of Graphene particles dispersed in an ink, enable easy printing onto substrates, reducing production costs and facilitating integration of the material into functional films.
Unlike Graphene monolayers deposited by CVD, the Graphene contained in these inks, generally obtained by exfoliation of thegraphite, can be deposited in thin layers (of the order of a few microns) using conventional techniques such as screen printing, paving the way for high-speed production.

At GRAPHENATON Technologies SA, we develop functional films from graphene ink printing and other innovative materials to accelerate the energy transition. Thanks to our technology, we design energy-efficient solutions , both in production and in use
Our printing processes operate at significantly lower temperatures than conventional machining methods, thus reducing energy consumption. Their low cost facilitates mass adoption and reinforces their role in the energy transition.
Our printing processes operate at much lower temperatures than traditional machining methods, lowering production energy consumption. Printing is also economical, encouraging widespread adoption of our solutions and actively contributing to the energy transition.
Our functional films meet our customers' environmental requirements in heating, production and Energy Storage.
- Heating system : our heated films offer heat diffusion primarily by radiation. Infrared radiant heating differs from traditional convection systems. Unlike conventional convection systems, it heats people and objects directly, without passing through the ambient air. This reduces the thermal gradient in the room and improves thermal comfort for users, encouraging them to turn down the thermostat to promote energy savings.
- Energy production : our photovoltaic cell films are designed using innovative, high-performance materials in photovoltaics, such as perovskites and Graphene. This enables us to free ourselves from the constraints of silicon recyclability and energy dependence on China, which has a veritable monopoly on silicon photovoltaic solutions.
- Energy Storage : our printed supercapacitors provide fast, efficient electricity storage, offering a credible alternative or complement to batteries for certain applications. Manufactured from abundant, recyclable materials, they accelerate the decarbonization of energy networks and mobility. More durable than lithium-ion batteries, they can withstand millions of charge/discharge cycles, limiting replacement and reducing the ecological impact of energy storage.
