New graphene-based recipes spur startups
At Mobile World Congress, a large stand regrouped different graphene-based prototypes from members of the Graphene Flagship consortium, all devoted to bring graphene into the mainstream, finding everyday life applications from re-enforced plastics to wearable sensors.

As a reminder, the Graphene Flagship is one of the largest research projects funded by the European Commission (with a budget of €1 billion over 10 years), it brings together over 150 academic and industrial research groups in 23 countries.

Ever since the first 2D graphene platelets were exfoliated from plain graphite, the wonder material has been tested in all sorts of devices, not only for its peculiar electronic properties but also for its mechanical strength and stability.

Spain-based industrial-grade graphene provider GrapheneTech was exhibiting various blends of graphene platelets, as powders, mixed into inks for conductive printing or into plastic pellets with various graphene weight percentages for injection molding. On the same stand could be seen 2D graphene monolayers on copper as well as graphene oxide layers on wafers from Graphenea.

Project manager at GrapheneTech, José Antonio Peláez Amador walked eeNews Europe through various applications, water-based conductive inks being promising for some printed electronics applications. The company boasts it produces one of the purest graphene in Europe via the solvent-free dry mechanical exfoliation of graphite (an abundant European resource). GrapheneTech also offers its graphene in a wide range of dispersions for functional fluids and coatings.
