Based in Spain, Graphenea has developed technology they believe solves some of the thorniest graphene production problems. The company has at least one method patent in its pocket.
Graphenea sells a series of graphene layers and solutions and graphene oxides in various configurations. However, Graphenea only delivers small quantities suitable for research and development. A four-inch wafer of silicon with a monolayer of graphene on it will set a scientist back $849.00. The budget minded researcher can order a one square centimeter of the some configuration for $59.00. Graphenea will spring for shipping on orders over $600. Thus the one problem that everyone needs to get solved - producing economically at higher volumes - is still beyond even Graphenea’s reach.
