Blackleaf – European Graphene Innovator at the Crossroads of Defense Tech

In the heart of France’s industrial research ecosystem, Blackleaf emerges as a deep-tech innovator spun out of CNRS/Université de Strasbourg in 2018. This startup’s mission is far from ordinary: to supply advanced graphene-based inks and coatings that dramatically improve performance (thermal management, EMI shielding, lubrication) while slashing carbon footprints. Blackleaf’s story is one of decade-long R&D, French government awards and fast-track scaling – all tuned to Europe’s industrial renaissance.

What makes Blackleaf strategically intriguing is how its technologies might serve Europe’s defense needs: high-performance conductive films for aerospace and military systems, advanced materials to reduce reliance on imported commodities, and dual-use products that straddle civilian and defense sectors. By integrating proprietary, eco-friendly graphene production in France, Blackleaf aims to deliver a local supply of a critical material. The following preview highlights key insights on how Blackleaf’s portfolio aligns with EU strategic autonomy and NATO interoperability goals, from its product scope to its role in EU/NATO programs – enticing defense analysts and policymakers to delve deeper in our full report.

Blackleaf is an academic spin-off deep-tech startup specializing in graphene-based conductive inks and additives. Its core technology is advanced carbon material production entirely in France. The company’s innovations map to Advanced Materials & Manufacturing (graphene composites, coatings) and Critical Technologies (battery and rare-earth alternatives) EDT categories.

Blackleaf contributes to European sovereignty by creating a domestic source of graphene that can replace high-performance materials often imported from China. Its products – conductive films for thermal management and EMI shielding, graphene-enhanced lubricants and concrete additives – align with multi-domain defense applications (aircraft, satellites, land vehicles). Blackleaf is engaged in Horizon 2020’s Graphene Flagship and has won French national innovation awards (I-Lab, France Relance).
