Innovative printed materials for a sustainable future
GTSA prints inks from innovative materials (including Graphene) on polymer 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 on polymer 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.

Chez GRAPHENATON Technologies SA, nous développons des films fonctionnels issus de l’impression d’encres à base de graphène et d’autres matériaux innovants pour accélérer la transition énergétique. Grâce à notre technologie, nous concevons des solutions énergétiquement efficaces, aussi bien en production qu’en utilisation
Nos procédés d’impression opèrent à des températures nettement inférieures aux méthodes d’usinage classiques, réduisant ainsi la consommation énergétique. Leur faible coût facilite une adoption massive et renforce leur rôle dans la transition énergétique.
Nos procédés d'impression fonctionnent à des températures bien plus basses que les méthodes traditionnelles d'usinage, diminuant la consommation énergétique de production. L'impression est aussi économique, favorisant une large adoption de nos solutions et contribuant activement à la transition énergétique.
Nos films fonctionnels répondent aux exigences environnementales de nos clients dans le chauffage, la production et le stockage d'énergie.
- Système de chauffage : nos films chauffants offrent une diffusion de la chaleur principalement par rayonnement. Le chauffage par rayonnement infrarouge se distingue des systèmes de convection traditionnels. Contrairement à ces derniers, il chauffe directement les personnes et les objets, sans passer par l’air ambiant. Cela diminue le gradient thermique dans la pièce et améliore le confort thermique des utilisateurs, les incitant à baisser le thermostat pour favoriser les économies d’énergie.
- Production d’énergie : nos films de cellules photovoltaïques sont conçus avec des matériaux innovants performants dans le photovoltaïque, tels que les pérovskites et le Graphène. Cela nous permet de nous affranchir des contraintes de recyclabilité du silicium et de la dépendance énergétique envers la Chine, véritable monopole des solutions photovoltaïques en silicium.
- Stockage d'énergie : nos supercondensateurs imprimés assurent un stockage rapide et efficace de l'électricité, proposant une alternative, ou une complémentarité crédible aux batteries pour certaines applications. Fabriqués à partir de matériaux abondants et recyclables, ils accélèrent la décarbonation des réseaux énergétiques et de la mobilité. Plus durables que les batteries lithium-ion, ils supportent des millions de cycles de charge/décharge, limitant les remplacements et réduisant l’impact écologique du stockage d’énergie.
