The GRAPHERGIA project was present at Graphene Week 2025 (September 2025, Vicenza, Italy) sharing its research progress and results with the European graphene community. The Institute of Chemical Engineering Sciences of Foundation for Research and Technology Hellas (FORTH/ICE-HT), our project coordinator and research work package leader, presented the poster “In-Situ Laser Reduction of Graphene Oxide on Textiles: From Lab-Scale Optimization to Roll-to-Roll Manufacturing”, explaining how this is a vital component for developing next-generation wearable electronics, energy storage, and smart fabrics.
The poster was explained by Natalia Kantouni (FORTH), and it is co-authored by Chrysanthi Paparouni (Adamant Composites), Despoina Batsouli (Adamant Composites) and Spyros N. Yannopoulos (FORTH).
“Using both pulsed Nd:YAG (1064 nm) and continuous-wave CO2 (10.6 µm) lasers, graphene oxide coatings were reduced on diverse substrates, including polyester, polyamide, and carbon-fiber prepregs. Optimized processing yielded sheet resistance values as low as 8–10 Ω sq-1, among the lowest reported for laser-scribed graphene on fabrics. Crucially, the method was upscaled to an industrial roll-to-roll (R2R) platform, producing meter-scale, uniform graphene-coated textiles, thus bridging laboratory research with industrial manufacturing feasibility”, highlighted Natalia Kantouni, PhD at FORTH.
